imshow always assumes a regular rectangular grid of pixels. To plot image data on a non-rectilinear projection, you need to use pcolor or pcolormesh.
You may also want to look at the basemap toolkit, which provides much better support for geographic projections. The ones included in matplotlib are essentially "toy" examples to test the infrastructure, but aren't really intended for advanced usage.
