I removed and extra set of parens, changed the unless to a if! and compressed out the extra whitespace and got us dead even. 
sub A { @_=(1);L:for(2..100){$i=@_;while(--$i){next L if!($_%$_[$i])}p
+ush@_,$_} }
sub M { for(1..100){push@_,$_;for(@_[1..$#_-1]){pop@_ and last if!($_[
+-1]%$_)}} }

print join(" ",@_),"\n";

I kept trying to think of how do this with maps and maybe come out with something different, but nothing has come to me yet

##Update##
just saw how to squish out a 3 more characters 
sub A { @_=(1);L:for(2..100){$i=@_;while(--$i){next L if!($_%$_[$i])}p
+ush@_,$_} }
sub M { for(1..100){push@_,$_;for(@_[1..$#_-1]){pop@_&&last if!($_[-1]
+%$_)}} }
