Is encoding OK with microformats?

This is what the source will look like for a phone number that’s part of the schema.org microformat for a small business:

<div itemscope itemtype="http://schema.org/LocalBusiness" class="address">
   <span itemprop="name">
   <a href="/" title="name">Business Name</a></span>
   <div itemprop="address" itemscope itemtype="http://schema.org/PostalAddress" class="address">
     <span itemprop="streetAddress">555 North 55th Street,</span> 
     <span itemprop="addressLocality">City</span>, <span itemprop="addressRegion">State</span> 
     <span itemprop="postalCode">55555</span>
   </div>
   Phone: <span itemprop="telephone"><script type="text/javascript">(function(){var ml=" 28(-041)",mi="36768066642155",o="";for(var j=0,l=mi.length;j<l;j++){o+=ml.charAt(mi.charCodeAt(j)-48);}document.write(o);}());</script><noscript>*protected email*</noscript></span>
</div>

I’m guessing this is probably not kosher.

And what if you have made a phone number into a link?

There is no established convention for semantic markup for phone numbers, but something like this should generate a link that’s understood as a phone number in most devices and browsers:

<span itemprop="telephone">
    <a href="tel:+1-888-888-8888">(888) 888-8888</a>
</span>

It there a way to do this with EEB?
