Hello,
Regarding the Tab order concern, sorry to say but right now there is no option in Theme Settings available for that. It requires Customization and this is beyond our limitations and support policy scope. Hope you can understand our limitations.
Under the Theme, following is the Tabs priority confirmed from the Test Site. Firstly three default WooCommerce Tabs appear which are Description, Additional Information and Reviews.
Then the Global Additional Tabs in order if they are defined and then the Custom tabs appear which are defined under the Product edit area: https://snipboard.io/qjOZLb.jpg
