Naomi - it would seem that you were looking at how DirectRT data files are written. If you're using MediaLab, you will want to use the question_order.csv file located within the byquestionnaire folder of your data location. ( [Experiment Location]\data\byquestionnaire\question_order.csv )
Within the question_order.csv file, you'll be able to find the order in which each item was presented to the user.
