Possible also that numeric boarding groups (thus not having groups with the same name) is also to nowhere imply that C+ is a cabin.
It's sort of implied that PS is higher than FC, but I wouldn't count on it. Aside from that, JFK-LAX PS fares have a non-stop routing requirement and online SDC always seems to follow fare routing rules (I've only seen system ignore them in IROPs rebooking cases). You could try agent roulette.
