The test was in fact as Turing specified. In addition to 30% being the challenge, as Stuart pointed out, Turing specified 5 minutes and an "average interrogator".
The more interesting point here, I think, is the discovery (not very surprising by now) that a program that can pass the true Turing Test is still narrow AI not applicable to many other things.
The chatterbot "Eugene Goostman" has apparently passed the Turing test:
As I kind of predicted, the program passed the Turing test, but does not seem to have any trace of general intelligence. Is this a kind of weak p-zombie?
EDIT: The fact it was a publicity stunt, the fact that the judges were pretty terrible, does not change the fact that Turing's criteria were met. We now know that these criteria were insufficient, but that's because machines like this were able to meet them.
