How are site: results ranked?

Hi Matt, If you do a site:website.com on Google, on what basis the results are ranked? Is this the order in which Google gives importance to each and every page in the website? Because most of the time the top listed pages get more search traffic. Pratheep, Bangalore, India Have a question?
