Deleting (trashing) Custom Post Types

Plugin permanently deletes Posts of Custom Post Type rather than Trashing them and after some digging this appears to be down to the use of wp_delete_post which isn’t equipped to handle Custom Post Types:

Simple change I made was post-expirator.php

line 485: if (wp_delete_post($id) === false) {
to
line 485: if (wp_trash_post($id) === false) {

Seems to be working well now unless anybody has had any problems?
