Very true.  But if there is no such documentation, then I think a
feature request is in order.

Now that you mention it, my previous speculations had more to do with
Array.Sort, not Listbox.Sort.  I do vaguely imagine considerations of
stability in listbox sorting that may not apply to array sorting.  Has
anyone observed instability in the listbox sort?  A single such
observation would put an end to that speculation.  (Of course, if we
can't find a case where the sort is unstable, that really doesn't prove
anything, though it would be suggestive.)

Best,
