Usually it's because they need an image already open on the canvas, or maybe multiple layers, or an alpha channel on the selected layer/image or no alpha channel, and many other reasons.

For instance, pyastro-set-dark-sky.py needs an RGB image as it is written "RGB*" in the source code, thus grayscale or indexed image will disabled it (although there is an * thus I'm not sure it should disabled when indexed or grayscale, Ofnuts or Rich2005 can confirm or disconfirm)

Yes "RGB*" means that the plugin is only active for RGB or RGBA images (ie, RGB images with or without alpha channels).
