This is a known (and short term) limitation. The iOS 7 release notes:
https://developer.apple.com/library/ios/releasenotes/General/RN-iOSSDK-7.0/
say:
"64-Bit Runtime
Notes
You can submit 64-bit apps for iOS 7 today that take advantage of the power of the iPhone 5s. Xcode can build your app with both 32-bit and 64-bit binaries included so it works across all devices running iOS 7. If you wish to continue to support iOS 6 then you need to build for 32-bit only. Next month we will be making changes so that you can create a single app binary that supports 32-bit on iOS 6, as well as 32-bit and 64-bit on iOS 7."
For reference, this was published in September.
