A hash is great if the data is sparsely populated, but if you make the keys sequential integers, why not go with an array?

my @array = @hash{ sort {$a <=> $b} keys %hash};

Incidentally, note that you're deleting hash elements while iterating over it. You're not supposed to do that.

Update: To keep a hash, try something like this:

my %hash2;
@hash2{ 0 .. (keys %hash)-1 } = map { $hash{$_} } sort {$a <=> $b} key
+s %hash;

It's really ugly, though :)

Update 2 ysth and Aristotle both caught me sleeping. Pay no attention to the man in the classical poet outfit.
