The "Catalog" you are refering to is an object not a function that 
returns a result. You can however call it as a function::

    <dtml-call "Catalog(meta_type='Folder')">

and it will return a list of results. You can then take the len() of 
this list.

    <dtml-call "REQUEST.set('searchResult', Catalog(meta_type='Folder'))">
    <dtml-var "_.len(searchResult)">
    <dtml-in searchResult>
    ... etc.
    </dtml-in>
