Facets supported both key\_script and value\_script in this manner:  
{  
"size": 0,  
"facets": {  
"by-hour": {  
"histogram": {  
"key\_script": "doc['media.created\_time'].date.hourOfDay",  
"value\_script": "doc['media.likes.count'].value +  
doc['media.comments.count'].value"  
}  
}  
},  
"query": {  
"bool": {  
"must": [  
{  
"term": {  
"stream\_id": {  
"value": "1b883b7b-364b-4b5d-b099-9e7ef329a445"  
}  
}  
}  
]  
}  
}  
}

What's the equivalent of this for aggregations under 1.2.2.?

The equivalent would likely be a terms agg on the key\_script expression  
(using the terms agg script capability), and then followed by a nested  
stats agg on the value\_script expression (using the stats agg script  
capability). Something like this:

"aggs": {  
"by-hour": {  
"terms": {  
"script": "doc['media.created\_time'].date.hourOfDay"  
},  
"aggs": {  
"bytes\_stats": {  
"stats": {  
"script": "doc['media.likes.count'].value +  
doc['media.comments.count'].value"  
}  
}  
}  
}  
}
