python3 does not manage script_name

[qmax]

Ubuntu 14.04.2 LTS
uwsgi-plugin-python3 1.9.17.1-5build5

Plugin ignores script_name given from nginx and does not modify path_info.

nginx.conf:

    location /test {
        uwsgi_pass 127.0.0.1:9000;
        include uwsgi_params;
        uwsgi_param SCRIPT_NAME /test;
        uwsgi_modifier1 30; # this should turn on this behaviour, but does not work
   }

uwsgi.ini:

    [uwsgi]
    plugins=python3
    chdir=path
    virtualenv=%(chdir)/ENV3
    wsgi=filename
    manage_script_name=1 # this also should turn on this behaviour, but also does not work
    socket=:9000

Result of GET /test/foo

    REQUEST_URI: '/test/foo'
    SCRIPT_NAME: '/test'
    PATH_INFO: '/test/foo' # should be /foo
