I think the fix is easy: make the "random" encoding deterministic.  
I've done it for PHP Markdown recently by adding a custom pseudo- 
random generator to replace the standard random function used by the  
algorithm. The new generator is seeded with a checksum of the email  
address; this makes it deterministic.

If someone wants to port that change to Perl, I'll be glad to help.  
Here are the relevant two lines of code from the `encodeEmailAddress`  
function of PHP Markdown:

    # Deterministic seed.
    $seed = (int)abs(crc32($addr) / strlen($addr));

    # Pseudo-random function.
    $r = ($seed * (1 + $key)) % 100;

(Note: $key is the index of the current character.)
