Feature request from stasleo, posted on GitHub Apr 14, 2016
There is no way currently to specify sort order for tabs added by module at frontend product page. Magento2 just loads tabs from A to Z by its module name.
For example, our extension adds "Product Questions" tab to a product page: http://magento2pq.demo2.aheadworks.com/cassius-sparring-tank.html
Its position is 1st and there is no any attribute to place it at some other position. It is obvious that most of our clients would prefer to make "Description" tab appearing first.

Same issue here - we also tried repositioning with after/before other tabs within the xml and it's not working either.

I got the temporary solution that use sequence module in your xml:
<module name='Your_Module' setup_version='2.0.0'>
<!-- Your tab will be added on the last place -->

Anything new on this? Kind of a bummer.
Why did you move this issue from Github to Forum? How on Earth it is 'not a bug'?
