You have to define the "fastcgi_pass" directive in both locations 
for this to work.

And, as Cliff already suggested, you don't really need nested 
locations here, it's better to define exact location for 
/css.php, i.e. something like this:

    location = /css.php {
        expires 30d;
        fastcgi_pass ...
        ...
    }

    location ~ \.php$ {
        expires epoch;
        fastcgi_pass ...
        ...
    }
