I'm not in a position to check until tomorrow, but I'm confident that I successfully test for the localhost address like so

I was wrong in the IP address that I test, but correct in the format and the fact that it works. You should be able to do PTR record checks by formatting in this "in-addr.arpa" format. An easy way to get this is from the output of "dig -x" which shows the question section in the "in-addr.arpa" format (and also in the answer section if it resolves).
