That was the last little magic piece, now it works for all 3 ways:
QGIS Setting
Command Line --lang option
or System Locale

I noticed that the current setup doesn't allow for temporary override of
a QGIS setting, it rather changes it, but thats a minor issue for later.

Here's my code for use in other plugins
http://apps.sourceforge.net/trac/qgismetaedit/browser/trunk/translate.py
This might be something good to roll into QGIS and made available via
the api so that all plugins can trigger translations if they want
without a whole new copy of the code.

In your main plugin file you need something like
import os.path
from translate import localeSwitch
currentPath = os.path.dirname(__file__)

class MetaEditPlugin:
    def __init__(self,iface):
        self.iface = iface
        try:
            self.QgisVersion = unicode( QGis.QGIS_VERSION_INT )
            # Apply translation if appropirate
            localeSwitch(self,currentPath,"metaedit")

Thanks,
