Unrelated to the apparent bug you've described, I've been using a
different mechanism to achieve the effect that (I think) you want. $?
does the right thing:

% false || true ; echo $?
0
% false && true ; echo $?
1

You can use the %? sequence in your prompt to see the exit value; what
I do is actually use the following:
%(?// %?? )

This expands to " 1? " after false && true, and the empty string ""
after false || true. I find this really handy as the prompt is
different enough to draw my attention after a non-zero exit status.

Hope this helps,
