'<' currently only applies to niced processes. I think there should be different indicators for realtime and idle priority and other scheduling classes. In top(1), scheduling classes are supposed to be encoded as fake nice values and a single indicator almost works since the indicator is numeric so it can indicate the scheduling class; however, the encoding is limited and broken; a non-numeric indicator of the class combined with a shorter numeric indicator of the the priority within the class might be better.
