They didn't rise because it was hot outside that day. They must have walked there on their own, since Sam mentions there's no signs of blood on the ground, but once it got warmer the Others connection to them must have been interrupted. Once they brought them back across the wall however, the temp dropped at night allowing them to rise again.
Was it warm that night they spent at the same place Ghost found them too? Because they were found by Ghost in the evening but the men didn't go searching for them at night. Othor and Jafer didn't move either that night, and were found by the Night's watch the day after.

I may be wrong, but I have always thought that Bloodraven and Bran shouldn´t be blocked by the Wall since they are the greenseers and their warging abilities should be much much stronger.
Yeah, that is what I have been thinking too, and I still do btw

I think when you're connected to the weirwood network the Wall is moot, and since the Children's magic probably is in the Wall they should be able to hack it...
But I mentioned it as a possibility, someone else could be using Mormonts raven. I don't think that is very likely though.
