Hard-coded English string in gradebook

When I set 'Drop X Lowest' in my gradebook, the gradebook shows "(Lowest n Dropped)" in English at the Total column while I choose a non-English language pack.

The trivial fix is:

However, I think it's better to concatenate the strings into a single parameterized string like "Lowest $a Dropped".
