Here's an adjusted version. I also added some cvars so you can easily modify the prefix, health and armor values. Once again, untested.

PHP Code:

#include <amxmodx>
#include <fun>
#include <cstrike>

#pragma semicolon 1

#define pluginName "RandomPlayerBenefits"
#define pluginVersion "1.0.0"
#define pluginAuthor "LadderGoat"

#define taskID 20874

new messagePrefix;
new terroristHealth;
new terroristArmor;
new counterTerroristHealth;
new counterTerroristArmor;

public plugin_init()
{
    register_plugin(pluginName, pluginVersion, pluginAuthor);
    register_logevent("roundStart", 2, "1=Round_Start");
    register_logevent("roundEnd", 2, "1=Round_End");

    messagePrefix = register_cvar("rpb_prefix", "AMXx");

    terroristHealth = register_cvar("rpb_thealth", "200");
    terroristArmor = register_cvar("rpb_tarmor", "100");
    counterTerroristHealth = register_cvar("rpb_cthealth", "250");
    counterTerroristArmor = register_cvar("rpb_ctarmor", "150");
}

public roundStart()
{
    if(task_exists(taskID))
        remove_task(taskID);

    set_task(60.0, "randomPlayerSelection" ,taskID);   
}

public roundEnd()
{
    if(task_exists(taskID))
        remove_task(taskID);
}

public randomPlayerSelection()
{
    new tPlayers[MAX_PLAYERS], tPlayerCount, ctPlayers[MAX_PLAYERS], ctPlayerCount;
    new playerName[MAX_NAME_LENGTH];
    new teamSelector = random(1);
    new chatPrefix[9]; // 10 characters for a prefix should be more than enough. 
    
    get_players(tPlayers, tPlayerCount, "ae", "TERRORIST");
    get_players(ctPlayers, ctPlayerCount, "ae", "CT");
    get_pcvar_string(messagePrefix, chatPrefix, charsmax(chatPrefix));

        set_user_armor(randomTerrorist, get_user_armor(randomTerrorist) + 100);
        get_user_name(randomTerrorist, playerName, charsmax(playerName));
        client_print_color(0, print_team_red, "^4[%s]^3 %s^1 was randomly picked and received an extra %i health and %i armor.", chatPrefix, playerName, tHealth, tArmor);
    }

    else if(teamSelector == 1 && ctPlayerCount)
    {
