The method called mylist should return a list. You could try to do something
like the following in mylist (untested, and I'm guessing what you really want
to do):

 <dtml-return "objectIds('MyZClassMetaType')">

The method you have returns a string as there is no <dtml-return> tag and so
the method will return whatever 'text' it evaluates to.

Hope this helps,
