Both orders are possible and there is no hard rule for when one is preferred over the other.
Different adjectives might behave differently. A quick corpus search showed that:
ist dafür zuständig dass is more frequent than ist zuständig dafür dass
ist schuld daran dass is more frequent than ist daran schuld dass
The view that the order of adjective plus dependant preposition is flexible is upheld by the observation that there are multiple possible topicalizations:
Schuld daran bist du selber.
Daran schuld bist du selber.
Daran bist du selber schuld.
Schuld bist du selber daran.
Finally, note that although your question was about Präpositionalpronomen, prepositional phrases do not behave differently.
