I testes an used on my server and it works fine.
Maybe you can do like my :

pawn Code:

public OnPlayerDeath(playerid, killerid, reason)
{
    SendDeathMessage(killerid, playerid, reason);

    pInfo[playerid][Spawned]    = 0;
    onjob[playerid]             = 0;

    /*-------| Most wanted |------*/
    pInfo[killerid][MostKill]   ++;
    pInfo[playerid][MostKill]   = 0;
    MostStar(playerid);
    MostStar(killerid);
    /*-----------------------------*/
    pInfo[playerid][Deaths]++;

    // gangs
    if(pInfo[killerid][gID] != -1 && pInfo[killerid][gID] != pInfo[playerid][gID])
    {
        gInfo[pInfo[killerid][gID]][gScore]++;
    }

    if(IsPlayerConnected(killerid) && killerid != INVALID_PLAYER_ID)
    {
        pInfo[killerid][Kills]++;
    }
    SetPlayerScore(killerid, GetPlayerScore(killerid) + 1); // +1 Score to KillerID
    GivePlayerMoneyEx(killerid, 15000); // + 100 to the killer
return 1;
}

I make most wanted on top on public playerdeath!
