We could use the error code, but if the script fails due to a system
error we don't know what that error code is. Thus, it is difficult to
guarantee a unique error code.

I changed the message to read as follows:

 Sorry your version of the Tcl/Tk libraries is 7.6 and is too
 old for GRASS which requires a Tcl/Tk library version of 8.0 or later.
 Reverting default settings back to GRASS text mode interface.
 Error in Tcl/Tk startup. If necessary, please
 Report this error to the Grass developers.
 Switching to text mode now.
 Hit RETURN to continue...

If there is any other error the output is

 Error in Tcl/Tk startup. If necessary, please
 Report this error to the Grass developers.
 Switching to text mode now.
 Hit RETURN to continue...

Is this OK?
