This looks fine although I am not 100% sure that the key codes are the
same in every platform.
However one crucial thing you must do is add a "pass rawKeyUp" line
for when you have not trapped the key. Otherwise none of the other
keys will ever work.
I guess if you have no fields this is not such an issue but no
keyboard shortcuts would work either I expect.

on rawKeyUp keyCode
  if keyCode = 65293 or keyCode = 65421 then
      send mouseUp to button "Select" -- Return or Enter
  else if keyCode = 65307 then
      send mouseUp to button "Cancel" -- Escape
  else if keycode = 65288 then
     send mouseUp to button "Clear" -- Delete
  else
     pass rawKeyUp
  end if
end rawKeyUp
