It has :-)
The problem is that some of the scores are negative, not positive.
However a way around this has just occured to me:
1. Run all negatively scoring tests.
2. Run positively scoring tests in highest-score first order.
3. Stop when we hit the threshold.
Should be easy enough to implement, and I'm in that part of the code at
the moment (though I'm going home now - maybe tomorrow).
