I don't really think so in general. Site B is going to rank better as there are 100 pages with topical and more focused information than the 10 pages on site A. That gives site B 100 focused keyterms while Site A only has 10 not so focused ones. On a page by page basis, though, If site B and A have 10 basically identical pages (and there was no dupe penalty) they'd likely rank the same except for a slight bonus due to internal linking structure funneling PR back up toward the top.
