SVG 1.2 tiny

I have made the .ai icons (Adobe Illustrator CS3) and they also contain gradient and transparency elements.

Until now I had to provide icons in the SVG 1.1 format (<!DOCTYPE svg PUBLIC "-//W3C//DTD SVG 1.1//EN") that allowed me to preserve
the colours and the opacity of the elements. Now I have to provide icons in the SVG 1.2 tiny format or SVG 1.1 tiny (<!DOCTYPE svg PUBLIC "-//W3C//D
TD SVG 1.1 Tiny//EN") but the gradients and the transparent artwork are rasterized.

For the tiny format I tried:

1. Save As > SVG (*.SVG)
SVG Option: SVG Tiny 1.2
And I received the following Adobe Illustrator alert:
"Gradients are rasterised
Transparent artwork is rasterized"
Also it embedded rough .png files (which is unacceptable for my clients, they want only vector, no raster).

2. Save for Web and Services:
SVG > SVG Tiny 1.2
And, in the preview window, the transparency part is changed into opaque.

Is there a plugin, script or other software that I should use?
Please let me know how can I handle this.

Thank you!
