[Zope-CMF] automatic workflow transitions

I have a specific question about scripting automatic workflow
transitions, and then a more general question.
Regarding scripting automatic transitions:
I have created a new transition (in a DCWorkflow) that I set up to be
triggered Automatically. I have created a script and set it as the
"Script (before)" for the transition. I would like for the script to
allow the transition only if certain criteria are satisfied.
My problem is that I am unsure how the script can "veto" transition.
Based on some docs I read, I tried raising an exception if the criteria
weren't met, but I wasn't sure what exception to raise. I tried just
raising the string "vetoed", but that bubbles up to the user. On a
hunch, I then tried returning 0 (if I didn't want the transition) or 1
(if I did), but then the transition always occurred. So evidentally my
hunch was wrong and the return value is ignored.
Does anyone know the proper way to set up an automatic transition with
veto power?
Now for a more general question:
I have a folder in a CMF site the contents of which should only be
viewable by authenticated users. That means that the content also
shouldn't show up in search results unless the user is logged in.
What is the best way to accomplish this goal?
(I tried various approaches already, and so far the best I've been able
to come up with is a new "members-only" state. After setting up that
new state, I tried to create a new transition from the published state
to the members-only state that is triggered if the content is under the
proper folder. However, I can't figure out how to make the automatic
transition not occur if the content is in some other folder. Maybe
someone can offer a better/easier way to accomplish my goal...)
Thank you,
