Dear harris Dimoliatis,
Because the Tiny MCE delete 'rel' property in Custom HTML automatically. So, you can choose 'None' editor (in Global configuration) and paste the code line to your module again:
<div class="block-skill">
<p>Lorem ipsum dolor sit amet, consectetur adipiscing elit. Proin tincidunt diam ac lectus tristique scelerisque. Quisque vitae libero sit amet turpis</p>
<div class="box-skill span3 first">
<div class="skill-inner"><input class="dial animated" type="text" rel="95" value="0" /></div>
<h3>Adobe Photoshop</h3>
</div>
<div class="box-skill span3"><input class="dial animated" rel="90" type="text" value="0" />
<h3>Adobe Illustrator</h3>
</div>
<div class="box-skill span3"><input class="dial animated" rel="87" type="text" value="0" />
<h3>CorelDRAW</h3>
</div>
<div class="box-skill span3"><input class="dial animated" rel="85" type="text" value="0" />
<h3>AutoCAD</h3>
</div>
</div>
Thanks
