See How do I shuffle an array?. 
@lines = <IN>;
shuffle(@lines);
print OUT @lines;

# or if 'shuffle' returns the shuffled list

print OUT shuffle(<IN>);

As far as moving elements from one place to another, just move them around, or use splice if you need some more "serious" movements: 
($lines[param('from')], $lines[param('to')]) =
   ($lines[param('to')], $lines[param('from')]);
