Proposed resolution:

Add a new section after [allocator.adaptor.members]:

Scoped allocator operators [scoped.adaptor.operators]
template <class OuterA1, class OuterA2, class... InnerAllocs>
  bool operator==(const scoped_allocator_adaptor<OuterA1, InnerAllocs...>& a,
                  const scoped_allocator_adaptor<OuterA2, InnerAllocs...>& b);
Returns: a.outer_allocator() == b.outer_allocator() if sizeof...(InnerAllocs) is zero; otherwise, a.outer_allocator() == b.outer_allocator() && a.inner_allocator() == b.inner_allocator().
template <class OuterA1, class OuterA2, class... InnerAllocs>
  bool operator!=(const scoped_allocator_adaptor<OuterA1, InnerAllocs...>& a,
                  const scoped_allocator_adaptor<OuterA2, InnerAllocs...>& b);
Returns: !(a == b).

The WP (N3000) contains these declarations:

template <class OuterA1, class OuterA2, class... InnerAllocs>
  bool operator==(const scoped_allocator_adaptor<OuterA1, InnerAllocs...>& a,
                  const scoped_allocator_adaptor<OuterA2, InnerAllocs...>& b);
template <class OuterA1, class OuterA2, class... InnerAllocs>
  bool operator!=(const scoped_allocator_adaptor<OuterA1, InnerAllocs...>& a,
                  const scoped_allocator_adaptor<OuterA2, InnerAllocs...>& b);

But does not define what the behavior of these operators are.
