Apologies, I hadn't yet read your mail message while I started digging
into this failure this morning, and the fact that the files got
reordered from what was expected in the output file confused me into
thinking ext4 was failing tests that where the 062.out file expected
successes, and I juped to conclusions.

I see there's an sort command at the very end of _extend_test_bed(), I
presume we should also add a similar "LC_COLLATE=POSIX sort" to the
other "find" command pipelines, and it's easy enough to filter out the
lost+found directory by adding a "! -name lost+found".
