First make structure of CO22-  then determine resonating atructure like in this molecule pi bond between C and O can resonate at 3 places. as there are 3 oxygen atoms bonded with carbon. Now to find bond order use this 
Bond order=Total bonds/Resonating      
                     structures
hence bond order for CO22- is 4/3=1.33
