for anyone interested I changed the function a bit to be used just like get_the_terms(..)

function get_the_terms_sorted( $post_id, $taxonomy ) {
	$terms = get_the_terms( $post_id, $taxonomy );
	function cmp_by_custom_order( $a, $b ) {
		return $a->custom_order - $b->custom_order;
	}
	if ( $terms ) usort( $terms, 'cmp_by_custom_order' );
	return $terms;
}
