Try this:

if [ ! -r filename ]; then

That should work. I tried this on a file called test with chmod 000 
then chmod 666 and on 000 the script was true due to the exclamation 
but false when the file was chmod 666 since the script then made it 
false.

The quick script I wrote is as follows:

#!/bin/bash

if [ ! -r test ]; then
echo "this file is not readable"
else
echo "this file is readable"
fi

HTH.
