tournament: rework the 'a_draw_is_one_point_each' test to handle any ordering

When getting the tests to pass one by one, the final test is to sort teams by
score and then fallback to alphabetical by team name when scores match. Since
the earlier draw test also results in two teams with one score, it kinda ruins
the flow by requiring solution to be sorting by team name already.
