A/B testing across wizard like page flow

I run this website http://www.gipote.dk where users can create ads to sell dogs, puppies and equipment for pets.

The ad-creation process is a wizard-like flow over multiple pages.

I want to change this wizard in several ways - not just the content, but the order of the pages - and want to A/B test the outcoming results.

The flow can end up in one of the following results:

No ad is created (the user aborts - we don't like that... ;-)
A "Standard-Ad" is created
A "Silver-Ad" is created
A "Gold-Ad" is created

Since we already use Google Analytics, I thought about using their "Content Experiment" module for this testing, but it seems to be for testing only 1 page's content at a time.

Any thoughts about how this could be accomplished? In GA or with another tool?

Bonus info: The site is created in Rails 3.0

I will be able to send the user to different ending-page-urls based on the type of Ad created.

The start urls will probably be:

www.gipote.dk/annonce/new (this is the current version)

www.gipote.dk/annonce2/new (the new version - a complete new controller)

There are gems to make this easy for you. See Ryan Bates's screencasts on Split and A/Bingo.
