Nor am I an examiner, but . . .
Give it a few months and order your pilot records from the FAA.
FAA
Airmen Certification Branch, AFS-760
PO Box 25082
Oklahoma City, OK 73125-0082
Send it a check for $10; it will refund the excess if it costs less than $10 to copy your file. See if this event is in your FAA file. At least you will know what it is in your file and what others can find out about you. You can see if the FAA regards your oral as a bust. Then, you can formulate an appropriate answer.
For what it's worth, I busted an oral and the examiner issued a pink slip. I came back a couple of days later, coughed up another fee, passed the oral and passed the flight, such as it was.
Of course, under PRIA, training busts can be uncovered.
Hope this helps a little.
