Is this what you are trying to achieve?

"z_spawn_old charger auto" already spawn special infected in random position

I'm really not sure what do you want to do , also there are multiple plugins that can spawn special infected

PHP Code:

#include <sourcemod>

#pragma semicolon 1
#pragma newdecls required

public void OnPluginStart()
{
    RegAdminCmd("sm_add_infected", Command_SpawnInfected, ADMFLAG_UNBAN, "To Spawn Random Infected");
}

public Action Command_SpawnInfected(int client, int args)
{
    SpawnRandomInfected(client);
    PrintToChatAll("\x04[Random Spawner] \x01Player \x03%N \x01has spawned random infected", client);
    return Plugin_Handled;
}

void SpawnRandomInfected(int client)
{
    int spawn = GetRandomInt(1, 6);
    switch (spawn)
    {
        case 1: CheatCommand(client, "z_spawn_old", "charger auto");
        case 2: CheatCommand(client, "z_spawn_old", "hunter auto");
        case 3: CheatCommand(client, "z_spawn_old", "smoker auto");
        case 4: CheatCommand(client, "z_spawn_old", "spitter auto");
        case 5: CheatCommand(client, "z_spawn_old", "boomer auto");
        case 6: CheatCommand(client, "z_spawn_old", "jockey auto");
    }
}

void CheatCommand(int client, const char[] command, const char[] item)
{
    int CmdFlags = GetCommandFlags(command);
    SetCommandFlags(command, CmdFlags & ~FCVAR_CHEAT);
    FakeClientCommand(client, "%s %s", command, item);
    SetCommandFlags(command, CmdFlags);
}
