The y/// is very sneaky, but why play games with that $s? If you want a 0, see if one of $% $- $? or $[ work for you. Here it is shortened to 43 chars and as an added bonus, its now strict compatible. 
#        1         2         3         4
#23456789_123456789_123456789_123456789_1234
$_=pop;y/A-Z/:-T/;$?=36*$?-48+ord for/./g;$?

    I wrote it as a function.

    The function should be usefully callable multiple times.

    Since you're well past my meagre 59 (from the use.perl thread), I might as well show it: 
    $_=shift;y/0-9A-Z/\0-#/;(s/.//,($a*=36)+=ord)while length
    Yes, no output-- the game rules were unclear that way, too. Using your tricks I can get down to -- 43. 
    $_=pop;y/0-9A-Z/\0-#/;($a*=46)+=ord for/./g
    If only the null byte were legal in y///, then the above could become 42... 
    -- jhi

      Assuming that 46 is a typo... 
      ($a*=36)+=ord   # 13 chars
$a=$a*36+ord    # 12 chars

      But as you say, the rules are rather murky, so its tough to judge what qualifies as a solution and what doesn't.
