You could also try, from your script, to create a scheduled job. It's the long way around, but then the before insert/update/delete rule would run the SncTriggerSynchronizer.synchronize(current); that you are probably referring to.
I too am trying to make this happen, but I need to pass some additional parameters, but if you could script the values into a Scheduled Script record correctly, it should set you on your way.
