>From the output of "crm_simulate -LUs" it's very hard to see that. My guess was that utilization even influences the initial score.
For example:

Allocation scores and utilization information:
...
native_assign_node: prm_stonith_sbd utilization on h16:
pcmk__clone_allocate: cln_DLM allocation score on h16: 18060
pcmk__clone_allocate: cln_DLM allocation score on h18: 15030
pcmk__clone_allocate: cln_DLM allocation score on h19: 15030
...

My guess it that the score from above is from utilization.
