Interesting! I'd have put PHP and C++ at the very top of the list, then reverse the whole list. As a rule, I'd much rather start with a language that makes it easy to spot massive vulnerabilities, and then move towards a speedier and more volatile language where needed.
I know what you probably meant, but if you put them at the very top of the list and then reverse it whole, they'll end up at the bottom again. Just saying.
