Ahhh, of course - I had forgotten that permutation falling out of the regex. In fact it makes me wonder if the regex is actually a bit nonsensical in it's current form. I think all this "(9[\-\. ]*7[\-\. ]*[89])" should get ripped out and just replaced with a simple check once we hit a 13-digit number.
