One thing that’s really important to remember about TCC is that you have to synchronize the custom fields for any new installation or anytime a UDF has been created in the front end. The feature and product integration packs only have the dictionaries for the standard fields. The custom dictionary is located in the [TCC Installation Directory]\customdictionaries directory.

It is also important to point out that these dictionaries are set by product version.  I.E. if your script is on 13a, you will need to synchonize with 13a, if you synchronized with 15a in TCC you still wouldn’t see the custom fields.
