Thanks for your reply and help. It works now.
The tooltip did not help as I use rating with a custom column. Also that my column is offered in the drop down. Anyhow I got what I like with the SQL tab.
For those who like to copy and paste please find here my sql. Replace "18" with the proper number of your customn column as shown in the tooltip on your screen.
SELECT book FROM books_custom_column_18_link
WHERE value IN (SELECT id FROM custom_column_18 WHERE value >=10 )
