I added an "aggregation=avg" to the cml:checkboxes element. I copied the job and ran it on the internal channel and submitted my judgments. The results came out in the hidden field "results_percentage", so at least that part works.
As for making test questions, I don't know how to do that, because as they said in their email, the choices are created dynamically in javascript. If he wants to completely re-do the way he's built the job, here's one idea I can think of.
For each unit in their csv, create new columns titled
"category_1_name"
"category_2_name"
"category_3_name"
"category_4_name"
Then split out the contents of the column "categories" into those columns. In the cml he would do
<cml:checkboxes label="" validates="required" instructions="" name="" class="" gold="true" aggregation="agg">
