Set type question - conditional calculations

I seem to be having trouble getting a "set" type question to assign a value of a variable if a condition is satisfied in the conditional logic. For example, this will work:

l: x
t: set
- if $someQuestion == 1 then A
and set the value of $x to "A" -- but this will not:

l: x
t: set
- if $someQuestion == 1 then $somePriorQuestion
the result of the set in that case, is that x will be set to "$somePriorQuestion" rather than than the value of $somePriorQuestion, which is what I would expect it to do. I have also tried {$somePriorQuestion}, calc ($somePriorQuestion), and other possible combinations, but no joy. it seems that the conditional set will only assign the actual text that follows the "then " to the question.

If this is the intended behavior, can I please make an enhancement request that the "then" branch be able to set based on calculations, etc.?

Maybe there is another way around this? I suppose I could use jump logic. FYI, here is some code I was trying to get working:

l: test
t: set
- random 1 2

l:
t: jump
- if $test == 2 then goto radio2

l: radio1
t: radio
q: choose one radio1
- a
- b

l:
t: jump
- goto test1

l: radio2
t: radio
q: choose one radio2
- a
- b

l: test1
t: set
- if $test == 1 then $radio1
- if $test == 2 then $radio2

l: display
t: info
q: Here are the values: test= {$test} radio1= {$radio1} radio2= {$radio2} test1= {$test1}
