That's the kind of error message I'd expect if you ran "phenix.refine
score.py" instead of "phenix.python score.py".
What are the inputs? I would think that at a minimum I would have to input

You would definitely need a PDB file and MTZ file - those will just be
additional command-line arguments. The script I sent you does not require
a sequence or estimated RMSD; it also assumes that the model is already
placed correctly in the unit cell. Phaser does require the sequence and
RMSD, however; is that what you really wanted to use? If you actually need
to place the model you might as well just run the full Phaser MR_AUTO mode;
otherwise you can use the MR_RNP mode. I had expected to be able to do it
phenix.phaser model.pdb data.mtz seq.fa model_rmsd=1.0 phaser.mode=MR_RNP
although that crashes, which I guess may be a bug. There are other ways to
get the same information but it is not clear what exactly you're trying to
