This is just an idea, so don't take my word for it..you may want to wait to see what other monks have to say. I've stumbed across this problem a few times (never had the initiative to find a solution though).
You COULD try sorting by the KEY of the hash (for the first value of age), then rebuild your hash so the value you are wanting to split on is first. An example, if you wanted to search for their zip code, just SPLIT your hash and JOIN it again with the zip code being the first thing before your delimiter: value = 12345||39||Somehere in Cali||Cali.
This is untested and just an idea, but hope it helps.
