Google changed the way nofollow links interact with total PageRank a couple years ago, see [webmasterworld.com...]

It's no longer true that "internal links can also take too much pagerank away from homepage.If you want to increase Google PageRank of your website Home page,try nofollowing unimportant internal links!"

This used to be called a kind of "PR sculpting" and Google made it not work - so dump the plug in and move on.
