That is a known issue and I would not say it is an issue with AutoSPInstaller:
https://autospinstaller.codeplex.com/SourceControl/changeset/108624
After many hours over this topic, I would recommend to avoid using Windows Server 2012 * With SP2010 if you plan to use PowerShell Scripting for the farm build.
I also believe there is a workaround, that I have not tested at, http://techmikael.blogspot.com/2014/02/installing-sharepoint-2010-with.html
Comments: Resolved with changeset 109744: Changes in this release:
- Much improved support for SharePoint 2010 on Windows Server 2012 R2; deals with PowerShell version issues by launching external PS windows/sessions where required!
- New function Get-MajorVersionNumber does... exactly that. Is now called in many other functions for better support of running individual functions on their own (e.g. creating web apps only)
- Fixed script halting if now Office Web Apps updates were found (issue 20487)
- New function Stop-DefaultWebsite allows this functionality to be executed inline or in a separate window for SP2010 on Win2012 R2 support
- AssignCert function updated to support parameters, again for SP2010 on Win2012 R2 support
- Support for having multiple web apps with Type = "Portal" (for re-using app pools)
- Fixed function AddToHOSTS to prevent duplicate entries
