Validation stops at the first validator that fails. I suppose it would be slightly more efficient to put the validators that are most likely to fail at the beginning of the list, though probably makes little difference (keeping validators that access the db, such as IS_NOT_IN_DB, at the end, though is probably a good idea -- no reason to hit the db unless all the other validators have passed).
