I agree with you, but you got me thinking. How about this: 
#usage: @result = st_complex sub { complex comparison }, sub { transfo
+rm }, LIST 
sub st_complex (&&@) {
    my $compare = shift;
    my $transform = shift;
    map { $_->[-1] }
    sort $compare
    map { [ $transform->(), $_ ] } @_;
}

#usage: @result = st_simple sub { transform }, LIST 
#note: comparison is string wise.
sub st_simple (&@) {
    my $transform = shift;
    &st_complex(sub { $a->[0] cmp $b->[0] }, $transform, @_);
}

The only shortcomings I can find are that sub NAME (&&@) won't allow you to call NAME { CODE } { CODE } LIST, only the first code block can be a bare block, and I can't thing of an effective way to combine the two into a single function like sort.
