The traditional/old Klingon way of keeping score involves cutting oneself (pe''egh), and this is the term still in use. (TKW p. 135)

A "tally" or "(total) score" follows the same tradition. They say mIvwa'mey, literally "scars" (even though, in traditional scorekeeping, the cuts turn to scabs and eventually go away). This term is also used for "census" or "headcount."

"Out of" is awkward. loSlogh pe''egh; vaghlogh nID "cut oneself four times; tried five times." This is the construction even if the person stopped after four and didn't really attempt the fifth.

Maltz wasn't sure how "statistics" would be distinguished from "tally" in this context, but maybe mIvwa'mey poj "tally analysis" or mI' poj "number analysis" would work.
