Advice: upgrade to vorbis-tools 1.0 from unstable, rather than downgrading.

You can do this easily by adding the unstable archives to your 
sources.list file and (important) setting a low (100<X<500) Pin-priority 
on packages from unstable. You can do this by adding the following lines 
to your /etc/apt/preferences file (copied from my woody machine)

Package: *
Pin: release a=unstable
Pin-Priority: 101

This is not a well-advertised feature of apt, but it works well. It is 
documented in the man page for apt_preferences. The packages from testing 
will still be the default. You will have to specficly ask for the version 
from unstable.

If you really must downgrade, then check this out:
