If you look at those scraper sites they fit exactly what I'm seeing on the sites that have moved up the rankings. Very few backlinks, even fewer to the pages that rank, very well organised internal link structure with many internal links duplicated on every single page.
Either external link weight is being counted much less or internal link weight is being counted much more or a combination of both.
IMHO this is either an error on the part of the coders or it is a phase we are going through while they rebuild the link map of the web.
