Actually, Illustrator's "screen" mode acts the same as in Photoshop. The difference here is because Photoshop works with RGB color mode by default and Illustrator works with CMYK.

If you want that black color would be transparent in "screen" mode you'll have to set the color manually in colors palette in CMYK color mode to C - 100%, M - 100%, Y - 100%, K - 100%. Same thing applies to "overlay", "lighten", "color dodge", "soft light" modes. I discovered this recently while experimenting with Illustrator.

I hope this helps you (if you didn't know that already :)).

Oh, and this walkthrough is really useful. I'll definitely try something like this.
