The while loop works on order what the DIRHANDLE gives out. This ofcourse isn't sorted on the dir basis. I modified it a bit to do the sorting. 
#!/usr/bin/perl

use warnings;
use strict;

my $dir = "/Users/ctp/perlwork";

# read all entries from dir and skip '.' and '..' directories
opendir (DIRHANDLE, $dir) or die "can't open $dir: $!";
my @list=grep !/^\.\.?\z/, readdir DIRHANDLE;
print "<HTML>\n<HEAD></HEAD>\n<BODY>\n";

# now we sort the list on directory basis
foreach my $file (sort {-d "$dir/$b" <=> -d "$dir/$a"} @list)
{
  print "<B>$file</B><BR>\n" if -d "$dir/$file";
  print "$file<BR>\n" if -T "$dir/$file";
}

closedir (DIRHANDLE);
print "</BODY>\n</HTML>\n";

Few extra pointers. Order of $b and $a defines whether dirs or files come first. You also could use -T in there. And use of @array before could be removed. Update: put your dir instead of mine :P.
