Type cast problem when doing custom_score query

Hi folks,

I'm trying to get custom_score query working so that it scores documents by
recency, but all I got so far is a
ClassCastException[org.elasticsearch.index.fielddata.ScriptDocValues$Longscannot be cast to java
.lang.Integer]

The idea was to index documents with a field having integer type timestamp
and then to compare it passing current timestamp parameter in the query.
How come that the indexed integer value became long?

And further question, if I change current timestamp in query to something
more long-like (1376823903 => 13768239030000) it still throws an exception:
ClassCastException[org.elasticsearch.index.fielddata.ScriptDocValues$Longscannot be cast to java
.lang.Long]

Here's the commands to reproduce:

curl -XPUT 'http://localhost:9200/test_longs_problem/'

curl -XPUT 'http://localhost:9200/test_longs_problem/albums/_mapping' -d '
{
"albums" : {
"properties" : {
"date" : {"type" : "integer", "analyzed" : false}
}
}
}'

curl -XPUT 'http://localhost:9200/test_longs_problem/albums/1' -d '
{
"date" : 1376823903
}'

curl -XGET 'http://localhost:9200/test_longs_problem/albums/_search?pretty' -d '{
"query": {
"custom_score": {
"query": {
"match_all": {}
},
"params": {
"now": 1376823903
},
"script": "_score * 0.2 / (3.16 * pow(10, -9) * abs(now - doc["date"]) + 0.05) + 1.0"
}
}
}'

throws

"error" : "SearchPhaseExecutionException[Failed to execute phase [query_fetch], total failure; shardFailures {[NSdeWzwNSIeLtGA1mtLTyA][test_longs_problem][0]: QueryPhaseExecutionException[[test_longs_problem][0]: query[filtered(custom score (ConstantScore(:),function=script[_score * 0.2 / (3.16 * pow(10, -9) * abs(now - doc["date"]) + 0.05) + 1.0], params [{_source=org.elasticsearch.search.lookup.SourceLookup@7249d155, now=1376823903, _fields=org.elasticsearch.search.lookup.FieldsLookup@4c4e5e11, _doc=org.elasticsearch.search.lookup.DocLookup@2d01d53a, doc=org.elasticsearch.search.lookup.DocLookup@2d01d53a, _score=1.0}]))->cache(_type:albums)],from[0],size[10]: Query Failed [Failed to execute main query]]; nested: CompileException[[Error: uncomparable values <<1376823903>> and <org.elasticsearch.index.fielddata.ScriptDocValues$Longs@41983ee7>]\n[Near : {... _score * 0.2 / (3.16 * pow(10, ....}]\n ^\n[Line: 1, Column: 1]]; nested: RuntimeException[uncomparable values <<1376823903>> and <org.elasticsearch.index.fielddata.ScriptDocValues$Longs@41983ee7>]; nested: ClassCastException[org.elasticsearch.index.fielddata.ScriptDocValues$Longs cannot be cast to java.lang.Integer]; }]",
