narse,

Well, there may be other things that bound you (this example just uses integers and can have dupes) but a simplistic brute force approach would be: 

#!/usr/bin/perl -wd

use strict;
my $tot = 0;
my $i   = 0;
my $x   = 0;
my @array;

while( $tot < 100 ) {
   my $x = int rand( 100 );
   $x = ( $tot + $x > 100 ) ? 100 - $tot : $x;
   $array[$i] = $x;
   $i++;
   $tot += $x;
}

$tot = 0;
foreach( @array ) {
   print $_, "\n";
   $tot += $_;
}
print "Total is ", $tot, "\n";

But I'm sure there are prettier approaches. But start with rand and perlfaq4 for ideas.
