Anybody know what options are available?

Chrome console allows the standard options:

'ä'.localeCompare('z', 'de'); // -1
'ä'.localeCompare('z', 'sv'); // 1

Google Apps Script appears to ignore:

'ä'.localeCompare('z', 'de'); // -1
'ä'.localeCompare('z', 'sv'); // -1

Other options are similarly unavailable:

// in German, ä has a as the base letter
'ä'.localeCompare('a', 'de', { sensitivity: 'base' });
// -> 0 in chrome,
// -> 1 in GAS

// in Swedish, ä and a are separate base letters
'ä'.localeCompare('a', 'sv', { sensitivity: 'base' });
// -> 1 in chrome
// -> 1 in GAS

Does it have anything to do with active user's locale? Or does GAS just have a stripped-down version of localeCompare? Or am I doing it wrong?

does GAS just have a stripped-down version of localeCompare

Yes, it does. It runs on Rhino (a JS implementation in Java), in which localeCompare ignores all arguments after the first one. For example, 

"a".localeCompare("b", "c", "d")

is obviously invalid in ECMAScript but runs in GAS, with the arguments "c" and "d" being silently ignored.

This is somewhat similar to the situation with toLocaleString which acts as toString.
