Doesn't this

This would not work since that usage of 'sort' is only for an array ref,
and the original ref was a hash ref.
Actually, the "sort" vmethod does work on hash refs as well as array refs.
It returns a list of hash keys that you can use to process the hash in the
sorted order.
The suggested code doesn't work because the original poster wanted to
sort by a value hidden two values deep in a hash of hashes.

That's what I said. You'll notice the phrase "that usage of 'sort'" in my
previous post.
