Try this footprint - "powered by dotclear" + intext: "add a comment". This footprint leads to find you dotclear blogs that has dofollow comments enabled. Save your google search setting to 100 results per page. You can install SEOQuake toolbar to check pagerank. Dofollow lists are no wander with this type of footprints though it takes a lot of time to arrange a good list.
You can do it easy with Scrapebox. It has an option to search exactly Wordpress blogs with your keyword inside.. "powered by wordpress" "your keyword" is also a good query for you to start (you can add extra options if you want to make your search further -> inurl, intitle...)
