Umbraco Razor Orderby custom property - asp.net-mvc

Question

I'm using a partial view in Umbraco v6.2.4 that's pulling a list of related articles. The script below works perfectly and uses the "Refactored.Umbraco.MVCExtensions" to pull out a view count of the articles. So far so good but I would like to order/sort the list of articles by the most popular article i.e. based on the view count. However, the view count is not part of the Umbraco Model so I don't know how to order/sort the list based on this or if there's another way of doing this?
#inherits Umbraco.Web.Mvc.UmbracoTemplatePage
#using Refactored.UmbracoViewCounter
#{
var articles = Model.Content.AncestorOrSelf(4).Children.Where(x => x.IsVisible()).OrderBy("articleCategory, articleDate desc");
int pagerank = 1;
string elementId;
<div>
<p class="h3">Most Popular</p>
#foreach (var item in articles.Take(6))
{
elementId = "content_" + pagerank.ToString();
<div class="items #elementId">
<span class="pagerank">#pagerank</span>
<a href="#item.Url">
<p>#(item.GetPropertyValue<string>("title"))</p>
</a>
<span class="views-counter"> #ViewCount.GetViewCount(item.Id, category: "articles", increment: false)</span>
</div>
pagerank = pagerank + 1;
}
</div>
}

You can use Linq to combine both lists and then sort, something like below, I assume you are using petapoco for view count table, I can't test code since I don't have your custom data table but I think you can move to right direction for here:
var db = ApplicationContext.DatabaseContext.Database;
var sql = new Sql()
.Select("*")
.From<RefViewCount>(new SqlServerSyntaxProvider());
var refViewCountList = db.Query<RefViewCount>(sql);
var articles = Model.Content.AncestorOrSelf(4).Children.Where(x => x.IsVisible()).Select(r => new {Item = r, ViewCount = refViewCountList.Where(v => v.nodeId == r.Id).Select(v => v.count).SingleOrDefault()}).OrderBy(r => r.ViewCount).ToList();
