I was just working on a project requiring the request work order only be automatically assigned to an assignment group and an external vendor. I ended up going to configurations and setting task assignments to auto assign. This allowed an assignment rule to set the dispatch assignment group then it looked at the state assigned to that group. Then as long as the vendor was listed as the assignment groups and locations covered match the vendor was auto assigned. the category field was used to accommodate skills. While this is so far off from the OOB process that is the use case. I thought it may be of some help here.
