you have a little error in your logic, that's why!

## ELSE here means EVERYTHING but "right"!
## Therefore every arrowkey but "right" goes to the next card!

Use this instead:


on arrowkey tKey
  switch tKey
  case "right"
      if the optionKey is down then
        go first card of next bg
    else
       go next card of this bg
    end if
  break
  case "left"
     if the optionKey is down then
      go last card of previous bg
    else
       go previous card of this bg
     end if
   break

   # Now let all other arrowkeys pass
   default
     pass arrowkey
    break
 end switch
end arrowkey

I tend to use "switch" since this makes scripts better readable than lots of 
nested "if... then" statements.
