A workaround for this has been posted here:
The workaround doesn't work for me quite as listed, because when I attempt to copy the "run" action, holding down command to hit command + c changes the action... but I can right-click on the "run" action for a .scpt, copy it, load a .scptd in the trigger, and then paste the run action in. Save it and it works. It would be nice to get this fixed, but there is at least a workaround.
