Quite hard to see what's going on with the use of nasty variables $} and @}.

A brief breakdown: 
# put some numbers into $_
$_="415250511528293422193223122519645759676174";

# fluff
$_{$_}++;

# set $} to an array ref
$}=[];

# split the chars of this ref : A R R A Y ( 0 x 8 a 6 f 0 a c )
@_ = (split//,$});

# split each set of two chars in $_ into @a
push(@a,$&) while s;..;;;

# set @} to contain the chars from @_;
@}=map$_,@_;

# set @_ to the first 6 chars of @}, which are "ARRAY("
{@_=map @}->[$_],(0..5);}

# into each scalars, put characters built from the @a and @_
$j=join'',map(chr((ord$_[0])+$_),(@a[0..3]));
$a=join'',map(chr((ord$_[1])+$_),(@a[4..10]));
$p=join'',map(chr((ord$_[4])+$_),(@a[11..14]));
$h=join'',map(chr((ord$_[5])+$_),(@a[15..20]));

# print out the four scalars
print join' ',$j,$a,$p,$h,"\n";
