It counts each iteration through the loop so you know which item you're
working with.  It works better when the code's not as FUBAR as originally
written -- s/b:

function AddPoints pPointsListA, pPointsListB
   put 0 into tCounter
   repeat for each item n in pPointsListA
     put n+(item tCounter of pPointsListB) into item n of tResult
   end repeat
   return tResult
end AddPoints
