I remember once as a passenger on a 727 while deviating around thunderstorms in cruise hearing some sort of wind noises and then a vibration. More than once over a period of perhaps 30 seconds, I saw the aileron vibrating rapidly for about a 3 second period. I believe it was the inboard aileron but I'm not 100% sure anymore.
On the 727-200, the outboard ailerons are locked out above 200 knots, so you're probably right, unless the lockout was sloppy.
