Re: command-line tweaking of "Open With..." settings?

It may well be that Apple has been making bad decisions regarding the
use of extensions.  However, it is clear that they HAVE made decisions:
Get Info is quite willing to base launch decisions on extensions.

That said, I'm willing to use another way, if it can be accomplished
in a robust and (relatively) simple manner.  Here is the situation:

  *  Most of the files are being created by a Perl script.  Some of the
     files, however, are being edited by hand (e.g., by BBEdit or vi).

  *  The files don't have ANY resource forks, but I suppose these could
     be added.

I'm willing to run a script over the files to set their Type or whatever,
if this will make for a more robust solution (eg, when someone else's
xyz file appears).  My understanding, however, is that these four-letter
codes are regulated, and I'm not all that interested in jumping through a
bunch of hoops with Apple to get this accomplished.

What specific procedure would you suggest that I follow?
