I'm trying to sort custom posts using multiple numeric meta values but I only has success when sorting with just a single meta key.

In resume, I've two numeric meta keys pwa_score and installs. I need to order the results fisrt by pwa_score and second by installs, both in descending order.

The code bellow works like a charm for sorting by pwa_score only.

$args = array(
  'post_type' => 'apps',
  'post_status' => 'public',
  'posts_per_page' => 20,
  'paged' => $page,
  'suppress_filters' => true,
  'category_name' => $slug,
  'meta_key' => 'pwa_score',
  'orderby' => 'meta_value_num',
  'order' => 'DESC'
);

$the_query = new WP_Query( $args );

In case of trying to sort by multiple numeric meta keys using the sample bellow the results are aways incorrect. Its orders by pwa_score first, but installs appears to be random.

$args = array(
  'post_type' => 'apps',
  'post_status' => 'public',
  'posts_per_page' => 1000,
  'suppress_filters' => true,
  'category_name' => $slug,
  'order' => 'DESC',
  'meta_query' => array(
    'relation' => 'OR',
    'pwa_score_clause' => array( 'key' => 'pwa_score', 'type' => 'numeric' ),
    'installs_clause' => array( 'key' => 'installs', 'type' => 'numeric' ),
  ),
  'orderby' => array(
    'pwa_score_clause' => 'DESC',
    'installs_clause' => 'DESC',
  ),
);

$the_query = new WP_Query( $args );

How can I proper achieve this orderby using multiple numeric keys?
