Here is a follow up sample that randomizes the order of scale response options. It doesn't have an impact on the response data--just the order in which the options are presented. Note that the custom item requires no special parameters such as the (v6) used in the example above. That's because only one response value is collected. Note also that this sample includes an accompanying .que file.
Note this sample was revised on November 18th, 2008 to include "values" for each of the radio options (see discussion below).
