With the current 220 (less 4) observations, find_orb predicts 125997 km at 18:39 UTC.
If I set find_orb's std dev filter to 1.5 it eliminates 8 observations and the closest approach increases to 133002 km.
If I follow your steps exactly I get the same values from EXORB/SOLEX. I have all the MPEC K12 and K13 files and while extracting all the K13A010 records should give something identical to the file you get from the DB query it doesn't seem to do so.
