Photoshop has a single, global setting to determine the scaling algorithm used, for everything. It is in Preferences > General > Image Interpolation.Setting this will make all image scale transforms use this algorithm. So set this to nearest neighbour, perform the scale, change it back, is the rather tedious solution.
