Ordering of responses odd in postgres

I've noticed something odd when viewing the responses for my questionnaires. I have 3 questions, and for all of them the user picks from radio buttons labelled "Very", "Fairly", "Not very" and "Not at all".

When we look at the results in the responses pane, the options are not listed in the same order across all 3 questions - take a look particularly at question 3. http://openlearn.open.ac.uk/mod/questionnaire/report.php?instance=1367&sid=1364&action=vall (fixed : http://openlearnacct.open.ac.uk/mod/questionnaire/report.php?instance=1367&sid=1364&action=vall)

Patch attached.
