Hmm, unless I'm mistaken the checksum field is:

  00 00 00 00 00 00 70 00

FWICS the problem is that one of the checksum variants evaluates to zero
and tar is rather lax on accepting null checksum string (with trailing
garbage) as zero.

My first thought would to improve the heuristic a bit by requiring
the checksum to contain at least one octal digit.
