BSDers tend to regard this as a compliment. :)
(Btw, I think the situation must be similar at least on other *BSDs.)

Hm... There is 'sysctl -n kern.osreldate' (it prints precise six-digit
values), but this is not usable everywhere, for example in jails.

config.guess is usable, but not very precise:

  checking build system type... i386-unknown-freebsd8.0
  checking host system type... i386-unknown-freebsd8.0

The same goes for uname. (For biber that we currently distribute, 7.1
or higher is needed.)

Give me some time to investigate if we have some other options.
