You cannot order by a meta value and date using ‘orderby` that way you are trying.
'meta_query' => array(
'featured_clause = array(
'key' => 'pin_home_page',
'value' => 0,
'compare' => '>=',
'type' => 'NUMERIC'
)
),
'orderby' => array('featured_clause' => 'DESC', 'date' => 'DESC');
do a search for “clause” on the WP_Query page.
