Mark,
1. It's "perusing".
2. A PDF of the current NCAA rule book can be downloaded (free) here:
NCAA Publications - 2011-2012 Baseball Rules (2 Year Publication)
3. One place you say R2 misses HP, another you say he missed 3B - I believe you meant 3B both times.
The ruling is NOT different in NCAA from what it would be in OBR & FED, despite Referee mag's assertion to the contrary.
As the question was presented it was impossible to answer because it never said whether the R2 had already passed 3B at the time the BR was retired at 1B. Therefore, we don't know whether the R2 was "forced" at the moment he missed 3B.
