rake TestTask problem with t.options

I am trying to understand some rake stuff better ..

I have a test that works fine if I do:
"ruby test/integration/tcp_test.rb -n test_job_create"

but if I try to do it in a rake file like below, it errors out. It
seems the t.options is the problem because I can get it to work
without that:

/usr/bin/ruby -I"lib" "/usr/lib/ruby/gems/1.8/gems/rake-0.8.7/lib/rake/
rake_test_loader.rb" "test/integration/tcp_test.rb" -n test_job_create

file to load -- test_job_create (MissingSourceFile)
