Changed numeric sorting to lexically resolving issue #851

[matsduf]

The elements in the list (array) in the sort expression are not guaranteed to be numerical. Changed to lexical sorting. Resolves issue #851.

I agree with removing numeric sorting where you did, but it should also be added where @v4asnsets and @v6asnsets are built up. I wanted to make a review comment at the relevant line but Github wouldn't let me.

I do not understand what you want to have added. Please copy the lines of code and comment how you want it to be.

@mattias-p, do you want line 340 to change from

                push @v4asnsets, join( q{,}, sort @{$asnref} );

to

                push @v4asnsets, join( q{,}, sort { $a <=> $b } @{$asnref} );

and the equivalent for @v6asnsets?

[mattias-p]

@matsduf Yes, exactly.

[matsduf]

@matsduf Yes, exactly.

Updated with that.
