I think the nomenclature, specifically 'active' vs. 'installed', may
be getting confused here. As 'man port' describes: "Installed ports
can be activated or deactivated without being uninstalled."
Installed-and-active ports are live, installed-and-inactive ports are
on your local system as (compiled) .tbz files (typically in
/opt/local/var/macports/software/<pkg>/) ready to activate.

Are you certain you have two 'active' versions, or do you perhaps have
two 'installed' versions of py27-scipy? (The inactive one can be
uninstalled to save space if you don't expect to need to downgrade.)
