ScoringMode
This isn't strictly required, but only because of a kind of hacky behaviour where `HUDOverlay` will recreate all components on a scoring mode change currently (see https://github.com/ppy/osu/blob/8f6df5ea0f7f721c630fc8cad93bb3eef869d1d9/osu.Game/Screens/Play/HUDOverlay.cs#L410-L418). Best we do this just in case that happens to go away in the future.
