I think maybe the judges can tell how important cases are based on the charges. I don't think the implication is that someone is somehow reviewing the case prior to it being heard and using some judgement based on some (likely unknown as it has not yet been presented) evidence to order them, but that charges that carry less penalty or that are are already classified as lesser (i.e. misdemeanor compared to felony) are sorted prior to ones that are not.
I don't think the people sorting the cases (which could be the judges themselves) have any additional information that the judge doesn't readily have available, so I'm not sure there's much room for bias of a substantial nature.
