  There isn't a good solution, unfortunately.  Perl hashes the name and uses that for ordering.  FreeRADIUS assumes that the attributes are an ordered list, independent of name.

  You can work around it by returning policy names in Perl.  Then in FreeRADIUS, check for those policy names, and add the correct attributes.
