I've got the same problem, and I am told that the problem is due to a lack of links to the pages in question. Simply being in the Sitemap is not by itself sufficient to guarantee a page appearing in Google.

So: make sure that the pages that are listed link to the ones that aren't, so some PageRank trickles down.

Thanks, but the point is I have the same script installed on another website that has 80% pages in index...

That site probably has a higher PageRank.

Is curious, I've launched it after the one with few indexed pages :)
