Honestly, not a fan. With no offence meant, this feels a bit gimicky and unnecessary. We've already got the rep system based on quantitative numbers, we don't need three new systems based on three new sets of arbitrary numbers.
I think there's a different opportunity here though. I think it might be helpful for users who consistently provide a lot of help in one area to be awarded a kind of badge that certifies that they probably know what they're talking about, to help members seeking help to filter through information. I don't think this kind of a badge could be automatically allocated, it would need to be allocated by a section moderator. For instance, in the study help forums, people who consistently post high quality and helpful responses (i.e. not 'the answer is 5x') could get some kind of a badge to let users seeking help know that you might be able to provide them with genuine help. Or something.
