Thanks for the reply.  I did use descending, but then the 'active' cards
are in the reverse order to what I want.  Mainly, I asked because I was
wondering about the mark(ed) property and whether or not it was supposed to
be considered in a sort.  IOW, is there any difference between
 sort stack "xxx" by fld "whatever"  and
 sort  marked cards of stack "xxx" by fld "whatever"

I've used a hidden fld to sort by to work around it.
