Not to mention that in most (all?) spoken languages numbers are big-endian.
From what I have seen, low numbers in Arabic are spoken/written little-endian (twenty five is five and twenty). Apparently German as well. The internet claims that historically large numbers in Arabic were also written out (as in when using number words rather than numerals) little-endian.
Numbers below 100 in German are little-endian. 85 is "fünfundachtzig" (five-and-eighty).
