An array of floats represented as strings causes json decoding to fail

[GoogleCodeExporter]

What steps will reproduce the problem?
When the json of a field in the api is like this:
"schemas": {
 "Person": {
"scores": {
  "type": "array",
  "items": {
     "type": "string",
     "format": "float64",
   }
}
}
}

The generated Go struct looks like this:
Person {
   Scores []float64 `json:"scores,omitempty"`
}

Then when the api returns something like 
{ "scores": ["1234", "234", "234"] }
The json decoder fails because it's expecting an array of float64s, but its 
receiving an array of strings.

This failure can be seen here:
