You cannot store Linux/Unix file permissions in a ZIP file.

Edit (after comments) by using the "external attributes" field inside the ZIP header these attributes can be store inside a ZIP file. GNU's unzip is apparently able to read that additional field and restore file permissions. ^{I'm not sure when this was added to the ZIP format as the early versions - coming from a MS-DOS world - did not have support for this.}

The TAR format - being a "native" Unix/Linux format - has been designed to include file attributes and Ant can create TAR files that will preserve attributes across all Linux/Unix operating systems.
