I tried find_orb first as well.
If you import the 183 observations from MPC into Exorb (
http://chemistry.unina.it/~alvitagl/solex/) and then load that into Solex and run a close encounters scan, you will end up with almost exactly the same result as is displayed on the jpl site. i.e. 0.0007 au.
You can also use Exorb to generate a large number of Monty Carlo data fits and then run them all though Solex to generate a histogram of close approaches.
