I ended up including it in CMFCalendar/configure.zcml:

   <!-- Load CMFDefault.skin first, we use the layer named "cmf" it  
defines -->
   <include package="Products.CMFDefault.skin"/>

   <include package=".skin"/>

   <include package=".browser"/>

... and it works as expected now. Thanks for the pointers!
