I think you mean the 'make.index.markup' parameter in the
DocBook fo parameter reference.  That document describes
post processing of index page ranges.

Maybe I'm being naive here, but aren't the indexterms
in a group processed in document order?  Shouldn't that
give proper order to the page numbers?  Is it possible
that a filter step is somehow accessing them in reverse order?

I'm not able to duplicate this problem.  My page numbers
in my index are in ascending order.  Can you supply a 
document that exhibits this behavior?
