Comment (by jadpm):

 I am attaching a refreshed patch which follows the structure used in
 `WP_Query` and provides:
 * support for `'orderby' => 'meta_value'` which will sort by the first
 `meta_query` clause fields.
 * support for `'orderby' => 'meta_value_num'` which will sort by the first
 `meta_query` clase field as a numeric value.
 * support for `'orderby' => 'meta_value'` combined with `meta_key` which
 will sort by the referenced field key, no matter wthether there is a
 `meta_query` entry for it or not, or even when there are no `meta_query`
 clauses at all.
 * support for `'orderby' => 'meta_value_num'` combined with `meta_key`
 which will sort by the referenced field key as a numeric, no matter
 wthether there is a `meta_query` entry for it or not, or even when there
 are no `meta_query` clauses at all.
 * support for 'orderby' => 'clause_key' which will sort by the referenced
 `meta_query` clause, if any, checking that passing a non-existing clause
 key will produce the default sorting.

 It also provides unit tests to cover all those cases.
