I think you'll have to add each item separately:

  get the mouseLoc
  add 14 to item 1 if it
  add 12 to item 2 of it
  put it

If you do it a lot you could make a handy addPoints function:

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