No, that doesn't have the same bug. The bug in the other code was because the join was done on the empty string, which makes the list (3, 5, 7) collapse to "357". When you quote an array, the implicit join is done on the special character $", which by default is a space. So: 
    my @a1 = qw/357/;
    my @a2 = qw/3 5 7/;

    print "@a1\n";
    print "@a2\n";

Different strings.

You could change $" to be something weirder when doing the comparison; something less likely to be found in a string normally. Like $;: 

    sub areq {
        local $" = $;;
        "@{$_[0]}" eq "@{$_[1]}";
    }
