There are other ways, but here is one:

my $string = 'address=no+3%2C+oxford+street';
(my $key,$value) = split(/=/,$string);
$value =~ tr/+/ /;
$value =~ s/%([a-fA-F0-9][a-fA-F0-9])/pack("C", hex($1))/eg; 
print $value;

actually there was an error in this line:

(my $key,$value) = split(/=/,$string);

should have been:

my($key,$value) = split(/=/,$string);
