Works fine for me on 3.6.5

There's a step missing from the reproduction instructions (thanks @abhi1693):

4. Click the "ASDOT" column header to order by that column, then reload the page.

The issue is that asn_asdot is actually an instance property rather than a table column, so we need to set the order_by accessor for the column to the raw asn value. This will fix the exception that occurs when attempting to sort the table by this column.
