In the US being arrested is the same as being charged, since police officers take up the role of prosecutors. But in any case, the question on schedule A relates to current or pending charges. There is one more question at the bottom which asks if you have been detained, your answer should be yes for this one.
There is one important thing to know, which is that you have *not* committed misrepresentation whichever way you answered IF you have included the FBI certificate showing the DUI arrest as part of your application. This is because you can argue that you misunderstood the questions (as apparently you do) and that the correct information can already be found elsewhere in the application. There is a court precedent for this, and you can appeal the misrepresentation ban if it occurs with a competent immigration lawyer who will take care of it for you.
The level of personal disclosure on Canadian immigration forms is very high. You are expected to detail any occurrences of being handcuffed or locked up at any time or place and for any reason, including instances where this has happened to you as a child. You are also expected to disclose your life history in detail (where you worked, studied, traveled, address history ..etc) not just for the last 10 years but for any period as the officer may choose.
