The which command assumes that the launch process already knows the  
information, in general by parsing some profile resource file.
Using "which tex" at startup will work from the Terminal but not from  
another application because the PATH variable is not set like for  
The first idea is to let the application parse those resource  
files... rather hard at first glance.
The second idea is to ask the terminal to retrieve the information  
and send it back to the caller.
In short

TeXShop asks AppleScript to ask Terminal to return the result of  
"which tex"

and I do not mention the way back to TeXShop once the information is  
In practice, this is not as efficient as storing all the relevant  
full paths a priori

Moreover, knowing the path a priori give a better user experience  
because it allows to make a more explicit user interface
