The 6.1 number is the correct one.
If you replace the z-matrix geometry with a cartesian one and run it through NWChem 6.3 again,
you will see that now the 6.3 and 6.1 energies agree

H 0.00000000 -10.08104973 -0.00000000
The bug present in 6.3 was fixed in 6.5 that was just released a few days ago.
I strongly encourage you to move to NWChem 6.5
