Inconvenient Managed Properties: when strings are numbers

Recently I wrote a blog post on how standard Managed Properties are not enough for supporting particular scenarios. For example, when building content aggregations sorted on dates or numbers you would need a custom Managed Property. The reason for that is the fact that, although there are some Refinable and Sortable Managed Properties available out of the box with SharePoint, despite the type communicated in Search Schema, they return string data which makes them useless for sorting on numbers.
