Ordering results by post type not working (with SF pro)

We’re using Relevanssi with Search & Filter Pro on our website. On the main search page, we’d like to sort the results by post type, prioritizing the products over posts and pages. I tried the following functions:

add_filter( 'relevanssi_comparison_order', 'rlv_post_type_order' );
function rlv_post_type_order( $order_array ) {
    $order_array = array(
        'product' => 0,
        'page' => 1,
        'post' => 2,
    );
    return $order_array;
}

add_filter( 'relevanssi_modify_wp_query', 'rlv_orderby' );
function rlv_orderby( $query ) {
    $query->set( 'orderby', 'post_type' );
    return $query;
}

and

add_filter( 'relevanssi_hits_filter', 'products_first' );
function products_first( $hits ) {
    $types = array();

    $types['page']    = array();
    $types['post']    = array();
    $types['product'] = array();
 
    // Split the post types in array $types
    if ( ! empty( $hits ) ) {
        foreach ( $hits[0] as $hit ) {
            array_push( $types[ $hit->post_type ], $hit );
        }
    }

    // Merge back to $hits in the desired order
    $hits[0] = array_merge( $types['product'], $types['post'], $types['page'] );
    return $hits;
}

However, neither of them seem to work. The relevanssi_hits_filter returns an empty results page, even after rebuilding the index. The relevanssi_comparison_order just returns the results, ignoring the defined order.

Any ideas? Help would be much appreciated!
