Oops, Ruslan Ermilov pointed out to me that the "false" value of
$invalid_referer is an empty string, not "0".

http://nginx.org/r/valid_referers

Well, then the correct config example is as follows:

http {

map $http_referer $zone3 {
default 1;
~^. '';
}

map $zone3 $zone2 {
default $invalid_referer;
1 '';
}

map $invalid_referer $zone1 {
default 1;
1 '';
}

limit_req_zone $zone1 zone=zone1:128k rate=50r/s;
limit_req_zone $zone2 zone=zone2:128k rate=10r/s;
limit_req_zone $zone3 zone=zone3:128k rate=3r/s;

server {
valid_referers domain.com;

location /click.php {
limit_req zone=zone3 burst=12;
limit_req zone=zone2 burst=10 nodelay;
limit_req zone=zone1 burst=100 nodelay;
...
