Small php to ASP script conversion

I require a PHP script of approx 60 lines of code converting to ASP. The PHp file retrieves variables through the POST method from a Flash game, it then checks a text file on the server to see if the game played had a better score then a previous entry in the text file. If it does then the newer score is written to the file instead of the previous one. This project is for classic ASP by the way, not .NET.
