This is now done.  The syntax is as above.

Usage details are in the top of the script file.  It's easy:

1) login to spamassassin.zones.apache.org
2) sudo su - updatesd
3) /home/updatesd/svn/mkupdates-with-scores/revert-stable-update 1234567

DNS actually waits 16 minutes to update (just like for a normal update) 
to give the mirros that sync every 15 minutes time to sync up.  The 
update is run via the at queue.

The script *DOES* create the file 
rulesrc/scores/DISABLE-AUTOMATIC-UPDATES to signal the auto-update 
script build/mkupdates/mkupdate-with-scores to not update the update 
version info in DNS when run to generate a new update package.  The file 
is created whenever you run the revert-stable-update script to do a 
reversion.  To re-enable auto-update publishing simply delete the file 
from SVN.
