Couple of suggestions - "common score" and "goal" does not work at all. Perhaps it's your dialect but the correct answer should be "nil". The most common score in any sport is 0-0 so zero is the correct answer. A goal is a weird definition because a goal is a method of scoring, but is not a "score".
And "naming" could work for "to do with names", obvious answer but not incorrect.
