i am not sure as i have just provided you an answer based on google search.
By setting priorities in the Sitemap XML you can basically tell Google, "These URLs are MOST important, so if you have room in your index for my site, index these first. If you still have room for pages from my site then index these pages next. And if you still have room for pages from my site then index these pages next... etc.
Limiting your sitemap to the most recent 50,000 pages is not really a good idea if your site has tons of URLs. Sites like RealEstate.com have millions of URLs the majority of which would never be found by a crawler without 1) a sitemap or 2) millions of deep links.
