One nitpick that I'll comment on because it got me thinking (always a challenging task first thing in the morning... good lord, it's noon...):

I think the sort function you provided is only doing what you want by coincidence. When you say:

sort { ($a) <=> ($b) } keys %hash

The ()'s around $a and $b force the <=> operator to use list context. If we know that $a and $b will always be single (numeric) elements (as in this case), this will produce the correct behavior - but if they were lists, things would be different.

In list context, I believe <=> compares the two lists element by element - damn if I can find where that's documented, though. Brother monks? Anybody got a pointer?.

Disclaimer: Again, this is trivia, won't affect the code shown, and I need more coffee.

Peace,
