You can do that with messages (messages are called before the events) and put plugin's name above the custom plugin names in plugins.ini.
Code:
#include <amxmodx>
public plugin_init()
register_message(get_user_msgid("TextMsg"), "TextMsg");
public TextMsg()
{
new Text[32];
get_msg_arg_string(2, Text, 31);
if (equal(Text, "#Terrorists_Win"))
{
// Terrorists have won
}
else if (equal(Text, "#CTs_Win"))
{
// CTs have won
}
else if (equal(Text, "#Round_Draw")) // Should work
{
// Round draw
}
}
