Hi,
Thanks for using our plugins. I can help out here.
Right now the tickets are ordered by the published date. So the last ticket created shows first and the first ticket created shows last.
We do not have a feature for manual ordering of the tickets, if you think that is something you would like as a feature I encourage you to visit our User Voice Page and either upvote an existing request or make a new request there.

You can go to the WooCommerce Product List and do a quick edit and change the Publish Date for a ticket putting the tickets in order by time there will reorder on the frontend. So you want the ticket to show first with the latest publish date.
Let me know if you have any follow up questions.
Thanks
