What does the Old English word "Score" mean?

Good question, but there's an error. "Score" is not an Old English word. The Old English word was "skoru"; "score" is the Modern English word derived from that root.

the average age is classed as being three score years and ten

Player camping grann, No , that is incorrect . Three score years and ten is a figure from the Bible I believe for Man’s allotted span . 70 years is a lifetime

ikñ32 I knew that I knew that I didn't know I knew that but okay now take me to speakerphone take me off
