In addition, "bounds" must be a field of the "options" structure and
can not be given as a separate argument as in your first example.

Nice you got it working. The constraints feature is new, if something
should go wrong don't hesitate to speak up.

Note please that Octave Forge has an extra mailing list, which
probably should preferentially be used for everything which regards
packages. You could miss some announcements if you are not subscribed
there.
