我尝试过的：

add_action('init', function() {
	if( isset($_GET['update_products_arv']) ) {
		$products = wc_get_products( [ 'limit' => 500,'offset' => 200] );
		foreach( $products as $product ){
			$total_stock = $product->get_stock_quantity() ? : 0;
			if( $product->is_type( 'variable' ) ){
				$variations = $product->get_children();
				if( !$variations ) continue;
				foreach ($variations as $variation_id) {
					$variation = wc_get_product( $variation_id );
					$total_stock += $variation->get_stock_quantity() ? : 0;
				}
			}
			update_post_meta($product->get_id(), 'xx_stock', $total_stock);
		}
	}
});

add_action('woocommerce_product_query', function($q) {
	if( ! is_admin() ) {
		$q->set('orderby', 'meta_value_num');
		$q->set('meta_key', 'xx_stock');
		$q->set('order', 'DESC');
	}
});
