I recall successfully setting the selection in TeXShop via Applescript 
in the past, but I can't find the code that I used.  Below is a script 
that I use which includes some selection manipulation.  The script 
changes the contents of the selection and then repositions the point 
inside the selection.  I'm not sure it will be directly useful, but it 
may inspire some ideas and is a useful script in its own right.
