Three minutes of investigation led me to think that you're looking for
the variable "magic-mode-alist".  

I think that what's happening is that your scripts end in ".tcl" and
the way it used to work was that auto-mode-alist used tcl-mode because
of the filename.  [If the scripts don't end in .tcl, I don't see how
it ever worked without a hint inside the file.]  Now something is
overriding auto-mode-alist, and it might be the "magic" mode-guessing.

There are other possibilities, but the ones I thought to check don't
seem to have changed lately.  [e.g., interpeter-mode-alist]
