OK, it turns out that you cannot style any UILabel properties using the UIAppearance proxy.

While the UILabel class conforms to the UIAppearanceContainer protocol, a check of UILabel.h shows that none of its properties are marked with UI_APPEARANCE_SELECTOR, the prerequisite for the use of UIAppearance.

Bugger.
