I doubt if priorities have much effect. I found that it didn't seem to matter what they were set to. But I also found that it didn't matter what was listed in the sitemap either, because Google spiders and indexes what it wants. Now I use a sitemap that is easier for me to read and update... one without priorities and without indents for every tag (one line per item) and that seems to work fine.
