We see
`--numeric-sort'
Sort numerically: the number begins each line; specifically, it
consists of optional blanks, an optional `-' sign, and zero or more
digits possibly separated by thousands separators, optionally
followed by a decimal-point character and zero or more digits. A
string of no digits is interpreted as `0'. The `LC_NUMERIC'
locale specifies the decimal-point character and thousands
separator.
"no digits": say "non digits", and mention
"You'll be sorry if your lines don't start with a number, because
...", E.g.,
$ seq -f t%g 33|sort -un
t1
"If you want sort to peer into the line, only considering numbers
buried within, you'll have to do ..."
$ sort --version
