I ran into the same issue when implementing P3P on W3C's site. 

As your <EXCLUDE>/us/en/*</EXCLUDE> matches already everything after
/us/en/, the statements about <INCLUDE>/us/en/images/*</INCLUDE> are
invalid. 

The Specification says:
When INCLUDE (and optionally, EXCLUDE) elements are present in a
POLICY-REF element, it means that the policy specified in the about
attribute of the POLICY-REF element applies to all the URIs at the
requested host corresponding to the local-URI(s) matched by any of the
INCLUDEs, but not matched by an EXCLUDE element.[1]

To express, what you want, you might consider writing:
<META xmlns="http://www.w3.org/2001/09/P3Pv1">
     <POLICY-REFERENCES>
         <POLICY-REF
 about="http://www.mydomain.com/privacy/p3p/policy20020114_main.p3p">
           <INCLUDE>/*</INCLUDE>
           <EXCLUDE>/us/en/</EXCLUDE>
           <INCLUDE>/us/en/images/*</INCLUDE>
           <INCLUDE>/us/en/xml/*</INCLUDE>
           <INCLUDE>/us/en/js/*</INCLUDE>
           <INCLUDE>/us/en/templates/*</INCLUDE>
           <INCLUDE>/us/en/include/*</INCLUDE>
           <INCLUDE>/us/en/dictionary/*</INCLUDE>
					 <EXCLUDE>....</EXCLUDE>
     </POLICY-REF>

by <EXCLUDE>...</EXCLUDE> I mean excluding all the subdirectories of
/us/en/, that have a different policy then policy20020114_main.p3p

Another way is to have a different policy for those entrypoints:

<POLICY-REF
 about="http://www.mydomain.com/privacy/p3p/pol_entrypoint.p3p">
            <INCLUDE>/</INCLUDE>
						<INCLUDE>/us/en/</INCLUDE>
						etc..
</POLICY-REF>

You might want to subscribe to our list www-p3p-policy for further
feedback (send email to  www-p3p-policy-request@w3.org with subscribe
