You need to configure and explicitly enable plugins for them to get 
activated. It's a bit of a mess at the moment and the details will 
almost certainly change before becoming part of any official release, 
but at the moment you basically need two bits of macro configuration 
(replace "myplugin" with the name of your plugin):

# Tell rpm where to find myplugin DSO
%__transaction_myplugin %{__plugindir}/myplugin.so

# Enable the plugin (comma-separated list)
%__transaction_plugins myplugin

The latter part is the problematic one as there's no way to just "drop 
in" a plugin and have it work, more thoughts on the subject at least
