Duplicate values in a hash aren't a problem; only duplicate keys are. So if your tags are never repeated, you'll be fine putting each input line's tag as the hash key and the frequency as its value.

When it comes time to sort, you can only sort your hash on something that's in your hash. So if your hash contains the tags and frequencies, you can sort on either of those (see my last reply for how to sort on the values); but you can't sort on the header that you haven't created yet.
