On the snap, or on the ready??

[GPC2]

Third and 20 at the 50. A2 takes the snap, scrambles, and throws an interception to B3 who is tackled in bounds. B2 had roughed the passer A2. A accepts the penalty. Ruling: First and 10 for A at B's 35. Clock starts on the 'ready'.

I say FALSE, the clock starts on the snap since according to 3-4-3b: The clock shall start with the snap....if the clock was stopped because B is awarded a new series.

One of the senior officials stated that the National Federation interpretation is that the clock will start on the ready because B is not really awarded a new series. I of course disagree, and wanted to get the opinion of the 'community'.
