Haha, first of all, you're not bothering us.
That's what we're here for, and in contrast to some guys who really nag the living sh*t out of people, you have quite a pleasant way of asking stuff, believe me...
With "ranking system" I suppose you mean a kind of list, so that you can see for example: "You are #191 of 245 on this server" ? Is it more or less something like that?
I suppose it's some kind of plugin (quite possibly an AMX plugin) that does this. Since AMX can be "plugged" into MetaMod, i guess you could do the same on your home 'puter - IF it is such a plugin. Do you have the possibility to ask the server admin or other "regulars" on that server? Maybe they can tell you what it is.
However, I see a potential problem if the plugin is not programmed with bots in mind. I am really an ignoramus when it comes to coding and programming, but I think that bots and human players are detected in different ways, so it could happen that the plugin has problems detecting and ranking bots. Someone here once reported a problem with a plugin called PsychoStats (as the name suggest, a kind of stats/ranking plugin), but that was many, many dll builds ago... If I were you, I would try to search both the metamod and amx sites for ranking plugins and/or ask the server folks what they use, d/l and just try it out... if you run into problems, you know where to ask, eh?
