The AMB plugins provide certain functionality that are needed to work with ambisonics. The ambisonic decoder Ambdec will take B-format signals and convert them to speaker feeds, but you need to produce B-format signals! That's where the AMB plugins come in.
My most used plugin (for a 1st order project) is the "AMB order 1,1 mono panner". It takes a mono input signal, and produces a 1st order B-format signal. The azimuth (horizontal) and elevation (vertical) components can be controlled using Ardour's automation.
I presume you've read Jorn Nettingsmeier's papers on doing ambisonics productions? Just in case you haven't this is one of them: "A pop production in ambisonics: Using ambisonics as a production format in ardour" http://lac.linuxaudio.org/2010/papers/6.pdf

Also, I have to say I'm confused with the whole AMB plugins thing (I have read papers where people claim they use both AMB plugins and Ambdec during Ambisonics reproduction). What is their purpose?
