Cheap hackery abounds.

Include an accumulator into the query_loop chain.  Somewhat
surprisingly, very few tests fail, and those that do are due to
over-specific reporting requirements in the case of ties, so rewrite
those tests to be more permissive.

There are probably codepaths which ignore the accumulator completely;
they will still work, because the accumulator will return zero points
when it is asked to ->get_points().
