elastic search custom sorting by script sorting or custom fields or run time

Question

I have products in an elastic search and I want to sort products such as

first display one product from each brand and then next round of each product. if product is completed from the any brand then that brand will skip.

So, first pick one product from each brand then again one next product from each brand and go on till all the products are not completed and it is by pagination. example is given below.
