Maybe it depends on what you are trying to accomplish in the end, but my hunch is that you would have a far easier time using a Multivalued token, with each value of the token representing a row. This way, you can simply use a For Each Value activity to iterate through your one multivalue token. 

For example, call your MV token "%(Rows)" and simply iterate through the values with For Each Value, and each iteration of For Each Value will be a row. Much easier than using the Repeat activity =)

Your next question might be about how to create a multivalue token in the SDK Script. You might notice that the SetTokenValue function in the script takes an object as the value type (assuming C# here); you can pass a List<string> or an array of strings with your row values into the SetTokenValue function to create your own MV token in your script.
