Is there a way to score each individual match of a drag and drop?

Prompted by this same question by someone else I just had a quick go at this and came up with one way to make this work. 

Basically I created a MC question which can easily be scored by answer. Then I used a variable to keep track of how many correct items that are dropped on the target.  Finally, I added some slide triggers to select the appropriate answer from the MC question objects. 

As you can see I used an image over top of the MC question objects so they can't  be seen  nor interacted with. 

This allows you to report the correct scoring via the results page without any scripting, etc etc. 

Also note that I haven't included any logic to account for removing items after they've been dropped on the target or other similar "error handling"

I've attached my quick & dirty example.
