Ordering with custom field in the Category listing

Hello,
I need to sort my products (courses) based on a custom field I created called sort-order.
I gave the values which were the actual course numbers, 1109, 1204, 2100, 2102, etc. to each of the products sort-order field.

When looking at the Hikashop products list in the back end I can click on the sort-order tab and the products all sort fine. I set up the sort order in a View All products(Courses) in the Joomla menu/Hikashop options and the products all sort as expected when viewing All Courses menu in the front.

However, when looking at the products based on categories view, and an associated lising of all products(courses) on the select category page, I can not get the products to sort by the sort-order value properly.
Some of the items seem to be in the correct order, others do not.

For example, I set CPE2100, the first item to 1 and 9999. In both cases it will not move from the first spot in the list.

I do not see any where in the Categroy settings to use the sort-order value field I need to use to sort the products. I only see that sort value in the Products listing.

Please offer some assistance with this. Thanks.

Oh! I see the selection now. Its the Product listing area under the category settings. This is fixed now. Thanks
