Comment (by scribu):

 WraithKenny's query is correct, in syntax: the outer array contains the
 'relation', while the inner arrays contain the specific clauses. It
 doesn't make sense logically, though.

 > Does this make it possible to orderby a meta_value and not exclude
 records lacking the meta?

 'meta_query' does not have any bearing on order. See #15031
