Thank you!

This seemed to work, although I am finding an issue now, since the survey is shown question by question, after the question it should record the order for I get a blank screen and then after clicking next it will show the next question. This doesn't happen if I run the survey as a whole question group, but I need to show it question by question. Any suggestions for that?

Also, will the code you've shared previously work for randomized subquestions? For question type array, the answer options here are not randomized, just the subquestions (for which I would need to record the order)

Thanks again.

since the survey is shown question by question, 

Of course it doesn't work.
Always remember: javascript runs on the participant's machine. How can it write something into a question that is not loaded?

Therefore we always recommend to show "group by group" but put only one question into each group.
This gives you the flexibility to display one question per page, but at the same time you can use these workarounds that require several questions in one group.

For question type array,

In my post I showed only "single question" and "multiple question", no array.
But you may try to adapt it.
If you investigate the page with the webdevelopment tool of your browser (F12) you see
that in arrays there is a row (tr) and a answers-list.
 
The rest is equal.
