I've done things like:

  on print_element_report
      global ELEMENT_BACKGROUND
      unmark all cards
      repeat with i = 2 to number of cards of bg ELEMENT_BACKGROUND
          if <<the conditions you want to report>> then
               mark card i of bg ELEMENT_BACKGROUND
          endif
      end repeat
      sort marked cards of this stack by << the fields to sort by>>
      open report printing with template "elements_report"
      print marked cards
      close printing
end print_element_report

which seems to work OK - depends on the number of cards you have to walk 
thru.
