In mod.csv you need 
menufile,ui/objective_info.menu

In MapName.gsc find
init()
{
	
}
and below
maps\_zombiemode::main();
add
level thread maps\ScoreSolo::CheckScore();

Place ScoreSolo.gsc in WAWDirectory/mods/mapname/maps

Now make a backup of objective_info.menu - Just Incase - If you don't understand this part simply use mine. If you don't understand this part but you have modified this menu pm me or msg me to help.
Look for
name 			"objectiveinfo"

and now replace
from 
		name 			"objectiveinfo"
to
		itemDef
		{
			rect			PAUSESCREEN_MAP_RECT
			forecolor		1 1 1 1
			background		"objective_line"

			decoration
		}
