When look-up is occurring the possible provider
ordering is used instead of the scope returned provider
ordering. This causes incorrect matches when look-up
argument names that are produced by multiple providers (at
the same scope level) all providing the same requirement
name.
The scope order should be enforced as the de-facto order
and not the order that the storage unit finds (which is
hash based and varies depending on hash ordering).
