Safari auto open some files while not auto-unzipping zip,tar,tar.gz

I need .ica files to auto-open while not auto-uncompressing others. Seems as if the .plist isn't fully functional? autoopen of .ica files works, but I can't get Safari to stop uncompressing .zip files.

Unchecking the "safe" box isn't going to work as it ignores the .ica files.

What am I missing here? (everything is patched, including the latest Safari)
