I'd expect "B" being the first line here:

	echo a B c d | xargs -n 1 | sort

using sys-apps/coreutils-8.30 at a stable hardened Gentoo Linux, but it is "a". Is this a bug or a feature?
(origin use case was "lsmod | sort" where now the head line of lsmod isn't any longer the first line of the output.

This is just a matter of your locale (e.g. "de_DE.UTF8" ?)
that sorts letters without regard to case.

If you force C locale you'll get "B" first:

  $ echo a B c d | xargs -n 1 | LC_ALL=C sort
  B
  a
  c
  d


Adding "--debug" will show a warning and help diagnose such issues in 
the future:

  $ sort --debug
  sort: using ‘ca_EN.utf8’ sorting rules
  ...
  ...

As such, I'm closing this as not-a-bug, but discussion can continue by 
replying to this thread.
