I put together an article on extending the Rev message path for just 
such occassions:
<http://www.fourthworld.com/embassy/articles/revolution_message_path.html>

In reference to backscripts, I note there:

    Scripts inserted first take precedence over scripts inserted later.

So when you insert a backScript, it goes in bsck of any existing 
backscripts.

Fortunately, the opposite is true of the corollary to backscript: 
frontScripts.

With frontScripts, those inserted later are put in front.  So if you 
insert a frontScript and the Rev IDE is already loaded, your script can 
get system messages before the IDE gets them.

Note that the errorDialog message will only address execution issues. 
To trap for compilation issues you'll want to handle the 
scriptParsingError message.
