I suppose it depends on how it’s implemented. I’d love it if someone would come back and tell me ‘yes, in virtually all browsers, order of items will be changed only when necessary to satisfy the conditions of the sort.

What you’re looking for is whether or not the algorithm is ‘stable’. It is known that Firefox’s is not, while IE’s is. The javascript standard doesn’t require a stable sorting algorithm.
Edit: Firefox 3+ has a stable sort. Please see http://www.hedgerwow.com/360/dhtml/js_array_stable_sort.html
