This one returns a list of items ready for use in a Formulator list field.

The easyiest way for you is to use accessors.
Let's take a simple example, with an Account a belonging to category 
account_type/income.

a.getAccountTypeValue(), the standard category accessor, returns the category 
object at portal_categories/account_type/income. 

In your case, you need related category accessors from this the category 
object, like that :

portal_categories.account_type.income.getAccountTypeRelatedValueList( portal_type=Account )

which returns the list of Account object related to that category.

This of course works with all categories (getGapRelatedValueList, 
getDestinationRelatedValueList and so on)
