To find the median of a set of data, we arrange the scores in order from smallest to largest and find the middle value. In this case, there are 11 scores, so the middle score would be the 6th score when the scores are arranged in order.  
Arranging the data in order: 
$$ 55, 60, 62, 67, 70, 72, 74, 76, 77, 85, 90, 95$$
The 6th score is $72$, so the median is $\boxed{	extbf{(D) }72}$.
