$Form{$sorted_field} =~ s/\r\n/\s/g;
I expected this expression to replace newline characters with whitespace. What it does is replace newline characters with an s. So I thought, perhaps I should escape the "\s" special character with another \, that just replaces the newline characters with a \ and an s.
\s stands for a whitespace character in a regular expression. The right hand part of the substitution operator (the replacement string) is _not_ a regular expression, it's treated as a double-quoted string. Therefore you can't use regex escape sequences in the replacement string.
Just use whatever character you want the replacement to be.
$Form{$sorted_field} =~ s/\r\n/ /g;
