Method 1: Sort Data in Cells
You need to sort the range using the Range.Sort method
Set rng = ws.Range("A2:A" & ws.Range("A" & ws.Rows.Count).End(xlUp).Row)
rng.Sort key1:=ws.Range("A2"), order1:=xlAscending, Header:=xlNo
Also see VBA Excel sort range by specific column.
Method 2: Sort Data in Array
Or load the data into an array and sort the array. See VBA array sort function?
Note: The QuickSort algorithm was retrieved from the link above.

' 2-dimensional array of the data
Dim DataArray() As Variant
DataArray = DataRange.Value
' Sort data in 2-dimensional array DataArray
QuickSortArray SortArray:=DataArray, SortColumn:=1
' Load sorted data into ListBox
SortedListForm.SortedListBox.List = DataArray
End Sub

'Sort a 2-Dimensional array
' SampleUsage: sort arrData by the contents of column 3
