I want to sort an AoH. Not each hash by its keys, but the

The value of one of the keys? If you don't know *which* key in
respective hash, this appears to be pretty tricky...
Of course I know _which_ key. Each hash has a key "date_tm", I
want to sort all the hashes in the array by their date_tm value
which is in the format: yyyymmdddhhmm.
Aha, the keys have the same name.. Good! Then Randy's suggested code
should do.
As regards documentation, besides "perldoc -f sort", there is a FAQ
entry that is very much applicable to this problem: "How do I sort an
array by (anything)?"
