Product without price at the end of list (sorting by price)

[samstroy]

VM 2.6.6
After sorting by price (from low to hight) products, which have no price are placed in top of list.
I think, it looks more natural when after sorting by price (from low to hight) products, which have no price will be placed in bottom of list.
Please help to change the location of the goods at the sorting.
Thanks.

I am sorry, the task is not so easy with pagination and no one answers, that means no one is interested in anordering like that.
