As long as we have BackPAN, this information is useful, for one 
particular case.
Sometimes, you need to find when the module started to fail for some 
outdated Perl version. Often, this version is already removed from CPAN. 
This situation is really rare but I ran into it when dealing with old 
versions of Perl. And it was quite popular module.

Usually, less than 1 year. But I'd like to have access to recent FAIL 
reports though. If distribution Acme-A was last tested on platform X 
with Perl 5.12.0 and failed, I'd like to have access to this particular 
information regardless of when the report was submitted. PASS report for on Perl 5.28 or 5.30 on i686-linux platform? No one really needs 
the contents of every (or any for that matter) report.

The grade is useful even without the text. Full text for PASS reports is 
probably not really useful at all.

> * Are pass/fail counts older than 5 years useful to you? 3 years? 1 year?

Yes, especially for versions/platforms that are not being actively 
tested anymore.
