One solution is to also keep a second hash, a hash of array refs. For this hash, keys are the dates, and values are array refs of file names. You need an array because multiple files may share the same date. Sort the key of this second hash.

If the sole purpose of the first hash is to print this report, then forget about your first hash, and just use the hash I suggested here.

Also create the second hash, when you are creating the first one (by doing this, most likely you don't need to split '|').
