Script Preparation code:

const compareString = (a, b) => {
		if (a === null && b !== null) {
			return 1;
		} else if (a !== null && b === null) {
			return -1;
		} else if (a !== null && b !== null) {
			return a.toLowerCase() > b.toLowerCase() ? 1 : a.toLowerCase() === b.toLowerCase() ? 0 : -1;
		} else {
			return 0;
		}
};

const compareString2 = (a, b) => {
		const s1 = a ? [...a.toLowerCase()].reduce((prev, char) => prev + char.charCodeAt(0), 0) : 0;
		const s2 = b ? [...b.toLowerCase()].reduce((prev, char) => prev + char.charCodeAt(0), 0) : 0;

		return a && b ? Math.sign(s1 - s2) : Math.sign(s2 - s1);
};
