I am not absolutely sure but it looks like you need to use the latest definitions for fonts and shapes, e.g. DefineFont3, DefineShape4, in order to make use of filters.
So the bad news is that the current suite of classes used for creating Shapes and Fonts are not filter friendly. The good news is that it should not take much effort to simply convert the generated objects to use DefineFont3 and DefineShape4.
I have attached a flash file showing text with a drop-shadow along with a text dump showing how the movie is created. It is not the answer you were looking for but it does show how to create the effect.
