May be you have already solved the issue, anyway you can control where
vala puts the array length parameter using a CCode attribute [1].

In this specific case you should bind the JSObjectMakeArray in this way:

[CCode (cname = "JSObjectMakeArray")]
public Object.array (
        Context ctx, 
        [CCode(array_length_type="size_t", array_length_pos=1.1)] JSCore.Value[] arguments, 
        out JSCore.Value exception);

And then use in your code in this way (NOTE: I omitted the array length 
parameter since vala do that work for us)

...
        return new JSCore.Object.array( ctx, dirs, out err);
     }

HTH,
Andrea
