Calculate Position/Rank for returned post

Question

Here is the custom post declaration

function ts_result_reg() {
$labels = array(
'name' => _x( 'Students Result', 'post type general name' ),
'singular_name' => _x( 'Students Result', 'post type singular name' ),
'add_new' => _x( 'Add New Result', 'result' ),
'add_new_item' => __( 'Add New Result' ),
'edit_item' => __( 'Edit Result' ),
'new_item' => __( 'New Result' ),
'all_items' => __( 'All Results' ),
'view_item' => __( 'View Result' ),
'search_items' => __( 'Search Results' ),
'not_found' => __( 'No result found' ),
'not_found_in_trash' => __( 'No result found in the Trash' ),
'parent_item_colon' => '',
'menu_name' => 'Student Results'
 );
 $args = array(
 'labels' => $labels,
 'description' => 'Add new custom post type students result',
 'public' => true,
 'menu_position' => 5,
 'supports' => array( 'thumbnail','title', ),
 'taxonomies' => array( 'classes' ),
 'has_archive' => true,
 'rewrite'=> array ('slug' => 'tscheck'),
 );
 register_post_type( 'ts_students_result', $args );
 }
 add_action( 'init', 'ts_result_reg' );

The backend metaboxes

array(
            'name' => 'French',
            'id'   => $prefix . 'subject_french_exam_total',
            'type' => 'text_small',
            // 'repeatable' => true,
        ),

array(
            'name' => 'Business Education,
            'id'   => $prefix . 'subject_business_edu_exam_total',
            'type' => 'text_small',
            // 'repeatable' => true,
        ),

        ...

The front end query

 query_posts( array(
...
)
    ),
'posts_per_page' => 100
   )
);
?>
<table style="border:1px solid black" cellpadding="1.5" cellspacing="5">

    <tr>

    </tr>
    <?php if ( have_posts() ) : while ( have_posts() ) : the_post(); ?>
    <!-- Initializing count and sum -->
    <?php
        $subject_count=0;
        $subject_sum_total=0;

         $subject_french_exam_total= get_post_meta(get_the_ID(),'_ts_subject_french_exam_total',true );
         if($subject_french_exam_total):
         $subject_count++;
         $subject_sum_total+=$subject_french_exam_total;
         endif;

         $subject_business_edu_exam_total= get_post_meta(get_the_ID(),'_ts_subject_business_edu_exam_total',true );
         if($subject_business_edu_exam_total):
         $subject_count++;
         $subject_sum_total+=$subject_business_edu_exam_total;
         endif;

        $store_student_avg=array();
      if($subject_sum_total>0.1):
      $subject_avg_total= $subject_sum_total/$subject_count;
      array_push($store_student_avg,$subject_avg_total);
       endif;
    ?> 
    <tr>
    <td><?php the_title(); ?></td>
    <td><?php echo $subject_french_exam_total ;?></td>
    <td><?php echo $subject_business_edu_exam_total ;?></td>
    <td><?php echo $subject_sum_total ;?></td>
    <td><?php echo $subject_avg_total ;?></td>

<?php 
rsort($store_student_avg);
$arrlength = count($store_student_avg);
$rank = 1;
$prev_rank = $rank;
for($x = 0; $x < $arrlength; $x++)
 if ($x==0): ?>
    <td><?php echo $rank; ?></td>

   <?php elseif ($numbers[$x] != $numbers[$x-1]):
    $rank++;
    $prev_rank = $rank;
    ?>
    <td><?php echo $rank; ?></td>

   <?php else:
    $rank++;
    ?>
       <td><?php echo $prev_rank; ?></td>

<?php endif; ?>

    </tr>
    <?php endwhile;endif; ?>

Edited: In the above code(shortened) I need the positions(rank) for each post's average calculated. Seems the whole loop is not run in wordpress before the output, hence, the output for each post is 1 (screenshot of output). How do I solve this?
