After a little more experimenting...
For me, the bug appears when sorting using the pulldown menu; if i re-sort on the column header it sorts correctly.
I don't remember ever seeing this before on the edit page, but it did used to happen on the cut page, so perhaps the processing related to the source-tape has migrated this bug to the edit page.
It is actually quite a serious issue because it is hard to spot the occasional error in a long list of clips -making this issue nearly invisible. But at the same time means you cannot rely on a date modified sort being 100% accurate.
