No, you forgot to normalize _your_ data.  My data are already lowercase
words.  *grin*

Nice way of using the other approach (which, it should be noted, is
character-map independent, unlike the ord() approach.)  It can be trimmed a
bit, though...

  perl -nle 'BEGIN{%c=map{$_,++$c}a..z}$s=0;
             print if map({$s+=$c{lc$_}}split//),$s==100' <word file>


But I should have used -n as well...

perl -ne'$t+=1+ord($&)-ord"a"while/./g;print if$t==100;$t=0'

with much thanks to Peter Scott for suggesting $& instead of $1.
