I don't think you can use script and exec together. Try pre-start script instead. Or put the exec line inside the script stanza. Not sure how this works together with expect fork though.

EDIT: Take a look at this bug comment by Scott Remnant, the lead Upstart dev. It looks like it would apply to your config file, and it doesn't appear that it has been fixed yet. I still think you might want to try pre-start script, or experiment with expect daemon vs. expect fork vs. nothing. Assuming you haven't done this already, it can't hurt.
