I actually have sora 9sd brifters (ugraded to tiagra), and my tiagra rd and sora rd lying aorund now (for 9sd double). But if you do make the switch to 9 or 10 spd you may need to look into getting new cranks also. I am almost certain that my brifters would work for you in a 9 spd set up but my derailers would not as it looks like the sirrus has a triple set up.
