You have an off-by-one error.

for my $i ( 0 .. $#sortedList - 1 ) {

Your "You" is Katie?

$#ary is the index of the last element of @ary.
(normally equal to 1 less than the number of elements)

See perldsc, perlop.

perl -e '@_=(4,5,6); print $#_, "\n"'
perl -e '{local $[=1; @_=(4,5,6); print $#_, "\n"}'

Context-free coding: for my $i ( $[ .. $#sortedList ) {}

But see perlvar: the use of $[ is discouraged.
