Not sure, but I think your problem may be due to virtual host
"defaulting" for server names which apache does not know about. I
usually add a "dummy" server before any of my actual virtual hosts to
help me discover bad virtual host configs.

Anyway, here's how I do the www redirection:

<VirtualHost *>
        ServerName a.example.com
        Redirect permanent / http://www.a.example.com/
</VirtualHost>

<VirtualHost *>
        ServerName www.a.example.com
        DocumentRoot /var/www/vhost/a.example.com
</VirtualHost>

<VirtualHost *>
        ServerName b.example.com
        Redirect permanent / http://www.b.example.com/
</VirtualHost>

<VirtualHost *>
        ServerName www.b.example.com
        DocumentRoot /var/www/vhost/b.example.com
</VirtualHost>

This has the added advantage that the redirect is performed in the
browser, not the server. This increases the value of any caching which
is performed outside the server.
