You could start the player object playing, then test to see when you reach
the end and then set the playRate to -1 to play it backwards, then test for
the beginning, set it back to 1, etc.

Try this:

on mouseUp
  set the playrate of player 1 to 1
  play player 1
  CheckPlayer
end mouseUp

on CheckPlayer
  if the playRate of player 1 is 1 then
    if the currentTime of player 1 is (the duration of player 1) then
      set the playRate of player 1 to -1
      play player 1
    end if
  else
    if the currentTime of player 1 is 0 then
      set the playRate of player 1 to 1
      play player 1
    end if
  end if
  if the optionKey is not down then  -- when you want it to stop
    send "CheckPlayer" to me in 100 milliseconds
  end if
end CheckPlayer
