We are testing with a course with 900 students. Only 20 of those students have submitted tests and have scores in the gradebook. When we click on the odering tools we find the following order when descending

• (i.e. no score)
  100 %
  95 %
  87 %
  60 %
  35 %
  23 %
  0 %

and the reverse for ascending.

Our view is that the order should be with 'no score' after (or before) the 0 % i.e.

100 %
95 %
87 %
60 %
35 %
23 %
0 %

• (i.e. no score)
