You already have a split that does what you're describing in your update. 
@data = split /($RE{quoted})|\./;

By putting the "unless" portion in capturing parens, they are captured and included with the results. I think that when a dot is encountered, it will generate an empty data item, so you might want to grep out empty results. 
@data = grep length, split /($RE{quoted})|\./;

Update: Gah, that's not the same thing. You really need to do two passes: split as above, then join anything that isn't separated by an empty string element. Something like: 
my $accum;
@data = map {
          if ($length) { $accum .= $_; () }
          else { my $x = $accum; $accum = ''; $x }
        }
        split /($RE{quoted})|\./;
push @data, $accum;

Caveat: I can't test code today.
