CS professors do grade for clarity and not just "does it work/compile?" but as a matter of relative weight in a grading distribution I think it gets less attention, and necessarily so for the more challenging problems. Writing prompts have a simpler objective domain to test (grammar, word usage) so the bulk of the grade weight goes to interpretation and style, which is of course subjective.
