Not directly... Just against the raw disk prior to getting ASM on there. You have to run the test with parameters that mimic an ASM volume. page 13 of http://download.oracle.com/auth/otn/utilities_drivers/orion/Orion_Users_Guide.pdf?e=1295030387&h=255baf316919cc96bf23e94cc7708912 has an example of that.

I've got a question about ORION - is it possible to run ORION against ASM disks? I have checked the documentation which seems to be 10.2 still and it says no, but maybe there is some undocumented functionality in it? I also assume that write tests, even if they were possible with ORION, are still destructive. Any pointers apprciated!
