Microsoft Test Manager (MTM) picks the language settings from OS.  There is no easy way to force MTM to pick alternate settings – say you are using English OS but want MTM be right to left (for example, you are authoring tests in Hebrew).

Windows Registry Editor Version 5.00

[HKEY_CURRENT_USER\Software\Microsoft\VisualStudio\10.0\EnterpriseTools\QualityTools\MTM]
"FlowDirection"=dword:00000001

To roll back, you need to reset FlowDirection back to 0.

 

In Right To Left, this is how MTM will look -
