I thank this list for the helpful replies. The use of 'GROUP',
and some tinkering with SCALE values, solved the problem.

Follow-up question: I found the useful 'wms_group_title'
metadata item. Am I correct in thinking there is no equivalent
'wms_group_abstract'? My parent layer is currently displaying
the GROUP value (= Layer Name) as "abstract." (wms_group_title
would have been a better choice on the part of mapserv if
there is no slot for an explicit abstract.)
