Of course I agree that counting letters should be done with tr, so assuming that the strings could be longer and are not required to be of the same length, you're code has a potential subtle bug.

If both "yahoo.com" and "yahoo.commies.org" are to be searched for, its chances of finding the second are dependent on its position in the regular expression relative to the first. You would have to sort your strings by length and build your regular expression with the longest ones first.

My code has its own sort of bug(?) in that both "www.yahoo.com" and "yahoo.com" might be found in the string "www.yahoo.commies.org"... however, it works correctly given the poorly stated requirements.
