You will use the following slight different version code, with some additional hooked functions:

add_filter( 'woocommerce_get_catalog_ordering_args', 'enable_catalog_ordering_by_modified_date' );
function enable_catalog_ordering_by_modified_date( $args ) {
    if ( isset( $_GET['orderby'] ) ) {
        if ( 'modified_date' == $_GET['orderby'] ) {
            return array(
                'orderby'  => 'modified',
                'order'    => 'DESC',
            );
        }
        // Make a clone of "menu_order" (the default option)
        elseif ( 'natural_order' == $_GET['orderby'] ) {
            return array( 'orderby'  => 'menu_order title', 'order' => 'ASC' );
        }
    }
    return $args;
}

add_filter( 'woocommerce_catalog_orderby', 'add_catalog_orderby_modified_date' );
function add_catalog_orderby_modified_date( $orderby_options ) {
    // Insert "Sort by modified date" and the clone of "menu_order" adding after others sorting options
    return array(
        'modified_date' => __("Sort by modified date", "woocommerce"),
        'natural_order' => __("Sort by natural shop order", "woocommerce"), // <== To be renamed at your convenience
    ) + $orderby_options ;

    return $orderby_options ;
}


add_filter( 'woocommerce_default_catalog_orderby', 'default_catalog_orderby_modified_date' );
function default_catalog_orderby_modified_date( $default_orderby ) {
    return 'modified';
}

add_action( 'woocommerce_product_query', 'product_query_by_modified_date' );
function product_query_by_modified_date( $q ) {
    if ( ! isset( $_GET['orderby'] ) && ! is_admin() ) {
        $q->set( 'orderby', 'modified' );
        $q->set( 'order', 'DESC' );
    }
}

Code goes in function.php file of your active child theme (or active theme). Tested and work.
