score is 0 in the output? - RosettaScripts

Hello,

The following is my .xml script:

When I examine the score.sc output file, it looks like this:

SCORE:     score        rms     maxsub       time        description
SCORE:     0.000      0.710    441.000    830.000 200ns1-101_AB_0001
SCORE:     0.000      0.709    441.000    763.000 200ns1-101_AB_0002

and the scores at the end of the PDB files look like this:

TER                                                                             
maxsub 441
rms 0.71
score 0
silent_score 0
time 830

Why am I getting scores of zero?

To my understanding, the RunSimpleMetric movers should be scoring the pose at the point where I call them in the protocol for TotalEnergyMetric, RMSDMetric, and TimingProfileMetric. 

My intention there was to see the energy before and after the "iterate" mover (I realize there's a way to calculate the delta energy directly, but I was trying to see how the RunSimpleMetrics movers work). Is that not how I'm supposed to do it?
