As far as I know there is no strict method for this. I usually open the script from the netlogon share on the PDC and save it locally and make the changes I want to make.

Then, when ready to implement, I rename the existing_script to existing_script_old and copy in the new script as existing_script.

Finally (make sure replication works) copy from the netlogon share on the PDC to the repl$ share...and to the netlogon shares on all BDC's if you don;t want to wait for replication to kick in.

Hope this helps!
