Humm, I just counted manually and you're right, it is 79. I wonder why this prints 60:

print length("return$i if$_[0]==495;$a=join'',sort{$a<=>$b}"
            ."split//,pop;$i++;a((reverse$a)-$a)");

Anyway, nice improvements, I should've caught that sort one : )

You're double-quoting the code, which means that the variables are getting interpolated into undef 0-length strings.

And I can take it down a litter further massaging your code into this:

sub g{ 
#          1         2         3         4         5         6        
+ 7  
# 12345678901234567890123456789012345678901234567890123456789012345678
+9012
  return$,if($_=pop)==495;$_=join'',sort split//,$_;$,++;g((reverse)-$
+_)
} 

But I can't do one on my own... my own solution came in at 83 :(
