Try the following handler in your stack script:

on domenu choice
  if choice is "next" then
    go to next card of this bg
  else if choice is "prev" then
    go to prev card of this bg
  else if choice is not "first" and choice is not "last" then
    pass domenu
  end if
end domenu

Then for your NEXT button script, you can use

on mouseUp
  domenu next
end mouseUp

and an equivalent handler for the PREVIOUS button.
This will disable CMD-1 and CMD-4, and it will make CMD-2 and CMD-3 work
exactly like the buttons.
