You've got heaps more problems than that. The file you say is ffbonded.itp is different from the one grompp is finding, because yours doesn't have 1492 lines in it, and grompp says there's an error there.
I suspect you've started editing in your installation share/gromacs/top folder and gotten things confused. It will be best to start afresh with a fresh installation (and thus copy of share/gromacs/top). Or CHARMM in beta3 is badly broken somehow...

No, grompp deals with atom order sensibly.
