I’m not sure if it’s the same thing you tried via Applescript. My version doesn’t work very well in Mountain Lion or Mavericks; it worked great before that. (Actually, it can cause TeXShop to crash in Mavericks; I’ve reported this to Dick Koch.) Applescript is pretty finicky, though, so I thought I’d post it in case it gives you an idea for something that actually works.

Thanks.  I'm very new (today!) to Applescript, so mine was simpler, just 
an "open", and not even a posix filename.  But your warnings about 
flakiness make me worry.

What I've currently got in place is simply to require the user to have a 
root file that my engine can handle to find all the subordinate files. 
If each chapter has "%!TEX root = Book.Rnw" and that file knows about 
the chapters, it works fine for me.
