            new str[80], weapname[20];
            vInfo[vid][TrunkWeapon1] = GetPlayerWeapon(playerid);
            GetWeaponName(vInfo[vid][TrunkWeapon1], weapname, sizeof(weapname));
            format(str, sizeof(str), "stores %s in the trunk of the vehicle", weapname);
            return PlayerActionMsg(playerid, str); 
        }
    }
}

GetWeaponName doesn't return the weapon name, but it stores it in the string you gave, so it stores in weapname. So, use weapname to show the weapon!

Edit: Just noticed. You are using strcmp before you even did sscanf, so I doubt this works.
