+**Note**: Scopes are given a `priority` based on their fallback ordering. By default, scopes without a fallback are given a priority of `1000`; scopes with a fallback, but are also fallbacks themselves, are given a priority of `100`; and all other scopes are given a priority of `1`. Higher priority scopes are loaded first. This can be overridden by setting a scope's `priority` manually in the [settings](#settings).
