I'm facing a strang problem while sorting documents in mongoose.

I have a huge scheme named as Property that contain a price object something like this:

{
    info: {
        price: {
            price: 361000 // number
        }
    }
}

Property Model:

@Field(() => Number, { nullable: true })
@Prop({ type: SchemaTypes.Number })
price: number;

Now, I have to sort the properties via property price i.e info.price.price.

What I have done:

const properties = await this.propertiesModel
  .find({})
  .skip(skipBy)
  .limit(size)
  .sort({ "info.price.price": -1 }); // sorting

The results are not as expected:

{
    "info": {
    "price": {
        "price": 999000
    }
    }
},
{
    "info": {
    "price": {
        "price": 99900 // wrong 
    }
    }
},
{
    "info": {
    "price": {
        "price": 997000
    }
    }
}

The schema is already using the Number type for price but seems like it's sorting as a string somehow.
