The thing is, you don't put the zcmds under OnPlayerCommandText.
Example:

pawn Код:

public OnPlayerCommandText(playerid, cmdtext[])
{
    if (strcmp("/mycommand", cmdtext, true, 10) == 0)
    {
        // all
        return 1;
    }
    return 0;
}

You can't use the following under OnPlayerCommandText

pawn Код:

CMD:test(playerid, params[])
{
    SendClientMessage(playerid, -1, "test");
    return 1;
}

Example of what NOT to do:

pawn Код:

public OnPlayerCommandText(playerid, cmdtext[])
{
    CMD:test(playerid, params[])
    {
    SendClientMessage(playerid, -1, "test");
    return 1;
    }
return 1;
}

If you put the CMD:test under OnPlayerCommandText, it doesn't work, because you can only put strcmp commands under OnPlayerCommandText.
zcmd can be put anywhere on the script, just do it like I showed you.
Hope I helped!
