Column name ending with "From" generates invalid SQL #250

I've noticed something odd when I try to return an ordered list from a query that contains a column name ending with "From" (e.g. ActiveFrom). I've included the SQL that is generated when I try to sort on the ActiveFrom column.

WITH __Data AS (
    SELECT [dbo].[PromoPosts].[Id],[dbo].[PromoPosts].[ActiveFrom],[dbo].[PromoPosts].[ActiveTo],[dbo].[PromoPosts].[Created],[dbo].[PromoPosts].[Updated] 
    from [dbo].[PromoPosts] 
    ORDER BY [dbo].[PromoPosts].[Active, ROW_NUMBER() OVER(ORDER BY [dbo].[PromoPosts].[Id]) AS [_#_]
SELECT [Id],[ActiveFrom],[ActiveTo],[Created],[Updated],[Active FROM __Data WHERE [_#_] BETWEEN 1 AND 25

It seems like it's parsing the From and injecting SQL in its place. When I sort on a different column that does not end with "From" the query executes as expected. This throw an exception "The ORDER BY clause is invalid in views, inline functions, derived tables, subqueries, and common table expressions, unless TOP, OFFSET or FOR XML is also specified. Incorrect syntax near the keyword 'BETWEEN'."

The following is what the generated SQL looks like when sorting on the ActiveTo column.

WITH __Data AS (
    SELECT [dbo].[PromoPosts].[Id],[dbo].[PromoPosts].[ActiveFrom],[dbo].[PromoPosts].[ActiveTo],[dbo].[PromoPosts].[Created],[dbo].[PromoPosts].[Updated],ROW_NUMBER() OVER(ORDER BY [dbo].[PromoPosts].[ActiveTo]) AS [_#_]
    from [dbo].[PromoPosts])
SELECT [Id],[ActiveFrom],[ActiveTo],[Created],[Updated]
FROM __Data

Looks like a problem in the SQL query paging code. I'll get it fixed.
