Firstly, sort() does not maintain the order of identical elements so I'd use bsort() which you can find online somewhere, can't remember where... I believe it has a /reverse or /invert option, not at my computer right now.

Secondly, you should bsort columns in increasing order of importance, with the most important sort last.

I have a dumb for-loop procedure that does that. This requires multiple searches through the array, which might not be optimal, but once you write it, you'll never use sort instead of bsort again :-)
