Hi,

this looks like an error to me? I tried to order a terms aggregation by the  
value count sub aggregation an Elasticsearch 1.3.0 throws the following  
error: "ReduceSearchPhaseException[Failed to execute phase [query],  
[reduce] ]; nested: ElasticsearchIllegalArgumentException[Invalid order  
path [grades\_count]. Missing value key in [grades\_count] which refers to a  
multi-value metric aggregation]; "

My Aggregation looks like this (this is only a dumbed down version to  
demonstrate the error.)

"aggs": {  
"students": {  
"terms": {  
"field": "name",  
"order": {  
"grades\_count": "desc"  
}  
},  
"aggs": {  
"grades\_count": {  
"value\_count": {  
"field": "grades"  
}  
}  
}  
}  
}

Regards,  
Valentin

This does seem to be a bug. I have opened #7050  
[https://github.com/elasticsearch/elasticsearch/issues/7050](https://github.com/elasticsearch/elasticsearch/issues/7050) for this
