Version 1.2.1 has_child query with function_score can not access child's numeric field value

curl -XPOST 'localhost:9200/products/' -d '{

curl -XPOST localhost:9200/products/offer/_mapping -d '{

"properties" : {
"color" : {"type" : "string"},
"size" : {"type" : "integer"},
"price" : {"type" : "float"}

search script as:
curl -s -XPOST 'localhost:9200/products/product,offer/_search?pretty=true'
-d '{
"query" : {
"has_child" : {
"type" : "offer",
"score_mode" : "max",
"query" : {
"function_score" : {
"boost_mode" : "replace",
"query" : {
"bool" : {
"must" : [
{ "term" : { "color" : "blue" } }
]
}
},
"script_score" : {
"script" : "doc['offer.price'].value"
}
}
}
}
}
}'
echo ""

get exception:
nested: PropertyAccessException[[Error: could not access: offer; in class:
org.elasticsearch.search.lookup.DocLookup]\n[Near : {...
doc[offer.price].value ....}

Can function_score get child's numeric field as parent's score like version
0.90.x custom_score did?
