you only had to ask
/st bag <number> to set the bag number (0 is main bag, 4 is far left bag, keep the number between 0 and 4)
then just right click the shard count icon, that turns on (and off) the auto sorting, left clicking it just does a single sort (if you aren't auto sorting)
I'm guessing you know the other icons right click, like the healthstone for the summoner menu ?
And I'm trying to find someone to take over working on it, but had no joy as yet, if it did stop working though I'd only need to borrow someone's account for am hour or two to get it up and running again and you'd be back on track.
