No it doesn't. cgminer is the "default" that almost everyone uses and the current version doesn't even have CPU mining. The current version doesn't have script either, you gotta download a previous version but that's a different story. You gotta throw in a --script when starting it, otherwise it mines with SHA-256.

If you wanna CPU mine, you gotta download a specific CPU miner.
