Yes, we do support custom tags for ColdFusion and the creation of scheduled tasks. Send us a link to the tag in question and we'll review it and work with you to install it or you can use CFModule to utilize the tag - in fact often times you might find that gives you more flexibility. You can create a scheduled task through code or contact our support team for assistance. We do review scheduled tasks periodically and reserve the right to change the time they run or remove them completely if necessary in order to resolve any issues that may arise from the task running and creating the issues for the server.
