Sorting text column as numeric column WPF MVVM

I have a DataGrid which is binded to a collection of models. My model has a string property called Position which is of type string, but contains an integer value.

My problem is, when sorting this column values get sorted as 1, 10, 2 instead of 1, 2, 10.

Is there anyway to handle this MVVM style without handling the Sorting event of the DataGrid in code-behind? Bear in mind I cannot change the type of the property.
