the osx partition has in this case two boot options, osx and refit. 
You have to tell the firmware what to boot. 

bless --folder /efi/refit --file /efi/refit/refit.efi --labelfile /efi/refit/refit.vollabel --setBoot

to revert it 

bless --folder /System/Library/CoreServices --file /System/Library/CoreServices/boot.efi --setBoot

from within refit centos can be booted ...
