crawled properties from my asp pages not available on my search.asmx search result

Question

I have my crawled propeties scanned and indexed on my Search Express 2008. I can even see those asp pages are reported being using in Search Admin > metadata properties but those crawled properties aren't available on my search result from search.asmx QueryEx

for example: I have an asp page has the following meta tag, and I've mapped those crawled properties to managed properties and also did full crawl.
<meta name="ExpiryDate" content="3/28/2010">
<meta name="Contact" content="William Smith">
<meta name="dc.date.created" content="2/2/2004">
<meta name="dc.date.modified" content="5/8/2009">

when I have my QueryEX

select  title, path, fileextension,  HitHighlightedSummary, created, enddate, FileName, size, rank, author, write, sitename 
from scope()
where freetext('testing')  
and sitename = 'http://intranet'
and (fileextension = 'HTML' or fileextension = 'HTM' or fileextension = 'ASP' or fileextension = 'DOC' or fileextension = 'XLS' or fileextension = 'PDF'  )
order by rank desc

XML result (see .doc has enddate, created and wirte but none for asp page)
