It does sound like balling.  The beginner bee books I have read say do not
disturb newly packaged bees for a week to 10 days (depending on the book) else
the bees may reject the queen and ball her.  I guess the 4 days isn't quite
enough.
 
I don't know about the bees playing "see how many bees can fit into a queen
cage" but a guess is it may also have been an attempt at "balling the queen"
and the bees were attracted by the odor of the queen in the cage, where she
recently spent so much time.
