QueryTask outSpatialReference

I am working for a client that has a Tiled Basemap in one Spatial Reference (3857) and a Dynamic Map Service Layer in another Spatial Reference (wkt: PROJCS["USA_Contiguous_Albers_Equal_Area_Conic",GEOGCS["GCS_North_American_1983",DATUM["D_North_American_1983",SPHEROID["GRS_1980",6378137.0,298.257222101]],PRIMEM["Greenwich",0.0],UNIT["Degree",0.0174532925199433]],PROJECTION["Albers"],PARAMETER["False_Easting",0.0],PARAMETER["False_Northing",0.0],PARAMETER["Central_Meridian",-96.0],PARAMETER["Standard_Parallel_1",29.5],PARAMETER["Standard_Parallel_2",45.5],PARAMETER["Latitude_Of_Origin",37.5],UNIT["Foot",0.3048]]).

I figured out how to project the Dynamic Map onto the Tiled map but for some reason when I do a QueryTask it doesn't transform the dynamic data into the new projection. I have set the outSpatialReference to 3857 and it doesn't change it. My guess is the well-known text for the dynamic map is keeping it from changing coordinates. I even went into the REST Services and tried a Query from there with the new outSpatialReference and it didn't work. I have included images to explain what I did.

One thing I figured out is that if I use the GeometryService.project() method it will change the coordinates fine, but that is a much more cumbersome solution for the application I am building.

It turns out that QueryTask doesn't convert the coordinates when done on Event Layers where the shape is derived from other layers. FindTask does convert them, so we are having to rewrite things to work with FindTask in certain parts.
