Error in jquery and IE6-7 attribute selector

I am trying to implement a jQuery script to handle some areas inside an image map. I use $ ('area [shape = "poly"]') as a selector to get the areas of interest to me. It works fine in IE8 and Firefox, but does not select items in IE6 or IE7.
This is a test page that shows this problem. I don't know if this is a jQuery bug or am I doing something wrong.

<img id="img1" src="nothing.gif" style="width:300px; height:300px; border: 2px solid black" usemap="#map1"/>
<map id="map1">
<area shape="rect" title="rectArea" coords="126,112,231,217" alt=""/>
<area shape="poly" title="polyArea1" coords="274,72,262,70,251,68,240,67,228,66,217,67,206,68,194,70,183,72,181,63,192,60,204,58,216,57,228,56,240,57,252,58,264,60,276,63" alt=""/>
<area shape="poly" title="polyArea2" coords="241,194,235,193,228,193,222,193,216,194,196,119,204,117,212,116,220,115,228,115,237,115,245,116,253,117,261,119" alt=""/>
</map>
</body>
</html>

It shows 2 in IE8 and Firefox and 0 in IE6-7
Thanks, Guillermo

It works if you delay the value:

var areas = $('area[shape="POLY"]');

IE6. :

[title*="poly"]

(*= )

+2

Try the following: $ ("Area [shape = poly]")

I have this code correctly selected in IE6

    <script>
      $(document).ready(function() {
        $("#button").click(function(){
          $("div[shape=poly]").remove();
        });
      });          
    </script>

<button id="button">Button</button>
<div shape="poly">p</div>
<div shape="poly">p</div>
<div shape="s">s</div>
<div shape="poly">p</div>
<div shape="poly">p</div>
0
