"/_api/web/lists/getbytitle('listname')/items?$select=ID,Title,URL,OrderID&?orderby=OrderID asc" renders the orderId as string

when I execute this method I expect the returned results to be sorted by OrderId (which is a number field). However I believe the rendered results are in string and the order is messed up. the Order Id of 10 jumps on top below Order Id of two. How can I force it to render the orderId as a number so that the order is:

1 2 3 4 5 6 7 8 9 10?
