Why is the k backwards for a strikeout?

Could you explain the reasoning behind why the letter "k" is used in reverse for a strikeout in baseball scoring? It seems like an unusual choice and I'm curious to know if there's a historical or practical reason behind this convention. Does it have anything to do with the way the scorer needs to quickly and easily distinguish between a strikeout and other types of outs? Or is it simply a tradition that's been passed down over time? I'd love to gain a deeper understanding of this aspect of baseball scoring.
