It appears that the InputScope property doesn't have the converter attribute.
REPRO Blend or VS 2012:
New WP7.1 project
Add reference to the WP toolkit ("C:\Program Files (x86)\Microsoft SDKs\Windows Phone\v7.1\Toolkit\Oct11\Bin\Microsoft.Phone.Controls.Toolkit.dll")
Create a control of type AutoCompleteBox
Try to set the InputScope property from the property inspector
Error 1: The PI inspector doesn't show the property
Expected: The PI to show the property
Set the property in xaml to "Search"
<toolkit:AutoCompleteBox Height="153" Margin="79,84,76,0" VerticalAlignment="Top" InputScope="Search"/>
Build => builds fine
Restart Blend and open the project
Error 2: Blend reports parsing error!
"The TypeConverter for "InputScope" does not support converting from a string"
Expected: Xaml should be parsed just fine, as it is valid

The following attribute should be added to the InputScope property:
[TypeConverterAttribute(typeof(InputScopeConverter))]
