I would assume that any mod recruiting a programmer/coder would be primarily expecting one or both. Anything else is presumably down to the individual's own talents/abilities, and how much additional work they are willing/able to take on. The scale of the mod project in question would also have a lot of bearing on it. A team of a few people would necessitate multi-tasking, a team of, say, 30-50 not so much.

Writing scripts or writing various tools to make process easier

That's pretty much what I thought. Thanks for the answers.
