Because of parse-order issues, that will not work. If you want to 'include' 
page chunks which invlove looping sub-tags, you'll need to read them into a 
catalog variable. i.e.:

Variable MEDIAICONS <<EOV
[if-item-field media =~ /Paperback/ ]
<img alt="[item-field media]" valign=center
src="__THEME_IMG_DIR__icon_book.gif" border=0>
[/if-item-field]
EOV

You can put this directly in your catalog.cfg, or put it in a separate file 
and use an #include directive. Then reconfig your catalog. Place in on the 
page thusly:

__MEDIAICONS__
