    scores: Tolerate some messiness in the CategoryConvertFunc
    
    If the CategoryConvertFunc does not closely examine the values it
    receives -- say, if it's a test function that always returns the same
    category -- then bad things will happen when it is passed the "scores"
    category, corresponding to the new directory created by this function.
    There is no sensible thing a game could ever do with this besides to
    return null, so just skip it.
