You can tint a select area of your image with these options:

• -region 100x100+100+100 -fill red -tint 50%

for example.

You can still do what you want by creating a clip mask where the floodfill area is opaque and the rest of the image is transparent. Once you have a clip mask you can invoke it with the -clip command line option followed by the -tint option. Only the non-transparent area of the clip mask is tinted.

You can find some ideas about clipping here: http://www.cit.gu.edu.au/~anthony/graphics/imagick6.
