No, it is invalid markup.

As David explained, you cannot have text data directly inside an <ol> 
element, since the element's content model allows <li> elements only.

Unfortunately there is no markup specifically for a list header, which is 
what "BREECHES" is probably supposed to be. There are several options in 
practice. You could take the list header out of the list, putting it right 
before the list as a <div> element or some heading element. Then you might 
need some styling to achieve the same layout as you have now. 
Alternatively, you could put it inside a <li> element but use styling 
to make it appear as unnumbered and the value="1" attribute to make the 
first real list item have the number 1:

<ol>
<li class="lh" onMouseOver="this.style.color='red'"
onMouseOut="this.style.color='#A2A2A2'">Breeches</li>
<li value="1" onMouseOver="this.style.color='black'" 
onMouseOut="this.style.color='#A2A2A2'">Helsinki
V Cotton</li>
</ol>

Note: I removed the type="none" attribute, which is incorrect though valid 
(its declared type is CDATA, so anything goes as far as validation is 
considered, but HTML specifications allow a small set of different values 
only).

This has nothing to do with validation. Besides, the idea is wrong. Font 
size should depend on what is most readable to the user, not on the screen 
size, which varies between 0 and infinity.
