After investigating the issue, it seems like sorting is OK. On your screenshot the first five values ordered are: * 3:21:44 (3 hours 21 minutes 44 seconds) * 2:42:38 (2 hours 42 minutes 38 seconds) * 1:17:05 (1 hour 17 minutes 5 seconds) * 36:40.91 (37 minutes 40 seconds 910 milliseconds) * 17:40.34 (17 minutes 40 seconds 340 milliseconds) Based on the length of the strings you have said that the ordering is incorrect, and I have confirmed, however in fact the order is OK, only the formatting differences are confusing. Based on this I am setting this bug as Invalid, as the sort by cpu time works ok, the problem seems the formatting. If you have any ideas, let's discuss them, I'll be happy to improve this upstream.

See the attached screenshot which is quite explicit. NB: - Sorting by increasing order still kept them grouped, with the 3-items group put at the end. - This grouping didn't affect sorting by any of the other columns I had set up. This is certainly not a major issue, it is just puzzling and could be an inconvenience if the first group was larger.
