I get syntax error when trying to detect a radius for the /testblock command. Here's an example:
/testfor @p[x=258,y=35,z=16,r=3]

It works fine on 1.0.9 (Windows 10, non-beta) but whenever I test the same command on 1.1.0.9 (Android, beta) it doesn't work.

However, if I create a world on 1.0.6 (non-beta) and add that command to a command block and then import that world on 1.1.0.9 (beta) then it works, but only for that command block.

NOTE: I noticed an issue with similar title, but he had provided wrong information for that issue so it's unrelated to this.

(I have similar issue with the following command: /execute @p[x=263,y=35,z=28,r=5] ~ ~ ~ say hi)
