I have found this an interesting thread. I work in a therapeutic garden for children that is certified organic. My whole purpose in the garden is to bring about a more permie approach to the garden while still making it accessible to the people that use it.
What I have found with the organic standards is there is nothing that stops us from putting permaculture practices into place, in fact it is encouraged. You are right they do not allow for humanure, but I believe in the future that will change.
If you look on the attra sight there is much information on how to create a healthier, mono-culture, tree filled, hedge rowed plant rich, encouraging wild-life, ecosystem, for our 'gardens' than one would think. You just have to look.
It is a great site that actually discourages plowing, trashing the soil, and tries to teach healthier methods.
It is a struggle. Do I agree with everything on the site, no. But when you are working with people that 'think' they have loved the land, and really do love the land, it takes time, patience and understanding. The attra site has been very helpful to me in introducing many topics that never would have been looked at had it not been under their designation.
I have and am learning to work patiently towards the day I can introduce more permie ideas, with the understanding it will be under the guise of saving them money and time. That is okay by me if it teaches what needs to happen.
