Amazon only officially added support for books in Traditional Chinese in May of this year. Books sold by Amazon in Traditional Chinese are only delivered in KFX format, not KF8/AZW3. I do not know if this is due to a limitation in the KF8 renderer, which is based on an outdated version of webkit, or whether it is just intended to promote lock in to their ecosystem.
The KFX Output plugin for calibre can convert Traditional Chinese into KFX format when used in conjunction with the latest version of Amazon's Kindle Previewer. A KFX supporting Traditional Chinese is output by the Previewer for language codes of zh-CHT, zh-Hant, zh-HK, zh-MO, and zh-TW.
The KFX Output plugin works around the problem discussed in this thread by examining the source EPUB to see if the actual HTML content specifies a country code and if so moving it into the OPF before conversion.
Added: Currently KFX only supports horizontal text for Traditional Chinese, but it appears that Amazon is working on handling vertical text in the future.
