Labels and values associated with Top-N values in a range

[sdspieg]

In this spreadsheet (worksheet 'Aggregate') I am looking for a way to list the Top-10 from the values from columns like US, U etc. on the right. So for instance in Column N, I'd want the To-10 words from column A that have the highest value in column B (US) listed in declining order with the corresponding actual values from Column B next to them. Could anybody please help me in finding the right formula? Thanks!
