That's because Catalog() is the same as Catalog.searchResults(). So you 
could rewrite your code to:

   <dtml-in "Catalog(meta_type=['MyClass'])">
     <dtml-var "_.len(Catalog())">
   </dtml-in>

and then you'll see what you're doing wrong =).
Better use this:

   <dtml-in "Catalog(meta_type=['MyClass'])">
     <dtml-var "_.len(Catalog(meta_type=['MyClass']))">
   </dtml-in>

or you could use one of the count- variables to determine the number of 
objects:

   <dtml-in "Catalog(meta_type=['MyClass'])">
     <dtml-var count-meta_type>
   </dtml-in>
