Yes, sorry, I missed the "in script" part.

I still don't think it's that hard to do in javascript either. There
may be a pause between the file finishing playing and starting again
because the media subsystem has to finish decoding, possibly be
unloaded and reloaded and then re-load the codec setup before being
able to play it back again. But since this should be an interim
solution until the media subsystem is brought up-to-date, it's
probably acceptable.
