Not sure about 8.5 but in general create a param as a string with 2 pre-defined options as '366-574' and '548 and over' (or however you wan the
text to look)
In your select statement assuming the field is numeric try:
({param}= '366-574' and table.field in 366-574)
or
({param}= '548 and over' and table.field > 547)
