Thanks Shawn,
According: http://dev.mysql.com/doc/refman/5.0/en/group-by-modifiers.html:
When you use ROLLUP, you cannot also use an ORDER BY clause to sort the
results. ...

Thanks Martijn, Barry,
I was wondering whether it could be done in a single query.
I want users to decide how many countries they want,
and show world sales on top of report followed by the N countries.
This to enable relative country shares, both for reporting and
graphs.
For example, Top-10 countries + Rest in a pie graph.
So I need one additional row in the Top-N query.

Have you considered using the WITH ROLLUP modifier?
Select Country
, Sum(Sales) AS Sales
From myTable
Where Year=2005
Group By Country WITH ROLLUP
Order By Sales DESC
LIMIT 25;
