It does in the actual report. You quoted the summary on the cover page, which is speaking in general of the kind of surveys 451 does. What I actually referenced was iMore's summary of the 451 survey's conclusions. Again, "When it comes to Maps, the survey asked iPhone 5 and iOS 6 users if they had found any porblems in their use of Apple Maps"...
No, I took it from the cover page of that particular survey's summary.
The full summary states:

In short, 4,270 consumers were surveyed and a 32% said that they were likely to get the iPhone 5.
Those who already had an iPhone 5 or had an iPhone running iOS6 were asked additional questions regarding the map fiasco. Of those, 90% of respondents said that they did not have any problems, while only 3% reported their Maps experience as a very big problem.
