This one is not as tough as you're making it. Create a view that includes the count (or other statistic), then query it using an ORDER BY column DESC clause with your ROWNUM <= 10
example:
CREATE VIEW TOPTEN AS
SELECT THECOLUMN column, COUNT(*) columnCount FROM THETABLE
SELECT column columncount FROM TOPTEN
ORDER BY columncount DESC
WHERE ROWNUM <= 10
Hope this works for you.
