Here's the result from the host where hosted engine is running:

Status up-to-date                  : True
Hostname                           : xxxxxx
Host ID                            : 1
Engine status                      : {"health": "good", "vm": "up", 
"detail": "up"}
Score                              : 3400
stopped                            : False
Local maintenance                  : False
crc32                              : 3c9dd013
Host timestamp                     : 82115
Extra metadata (valid at timestamp):
     metadata_parse_version=1
     metadata_feature_version=1
     timestamp=82115 (Mon Aug  8 10:44:12 2016)
     host-id=1
     score=3400
     maintenance=False
     state=EngineUp
     stopped=False

And this is from the problematic host:

Status up-to-date                  : False
Hostname                           : xxxxxxxx
Host ID                            : 1
Engine status                      : unknown stale-data
Score                              : 3400
stopped                            : False
Local maintenance                  : False
crc32                              : 6c959fce
Host timestamp                     : 82149
Extra metadata (valid at timestamp):
     metadata_parse_version=1
     metadata_feature_version=1
     timestamp=82149 (Mon Aug  8 10:44:45 2016)
     host-id=1
     score=3400
     maintenance=False
     state=EngineUp
     stopped=False

It seems the score is the same on both host
