The bookmarks are stored under the com.macromates.bookmarked_lines  
attribute name.

It is an array of line numbers (stored as a property list).

One caveat is that it is (likely) gzipped -- the reason for this is  
that extended attributes has a size limitation, and I did run into  
that when storing the values as their “raw” property lists.

There is no indicator of this, so you need to fetch the value, try to  
decompress is, and if that succeeds, parse it as a plist, otherwise  
try parse the raw value as a plist -- here is the code I use:

     ssize_t len = getxattr(path, key, NULL, 0, 0, 0);
     if(len <= 0)
         return nil;

     std::vector<char> v(len);
     if(getxattr(path, key, &v[0], v.size(), 0, 0) != -1)
     {
         uLongf destLen = 5 * v.size();
         std::vector<char> dest;
         int zlib_res = Z_BUF_ERROR;
         while(zlib_res == Z_BUF_ERROR && destLen < 1024*1024)
         {
             destLen <<= 2;
             dest = std::vector<char>(destLen);
             zlib_res = uncompress((Bytef*)&dest[0], &destLen,  
(Bytef*)&v[0], v.size());
         }

         if(zlib_res == Z_OK)
         {
             dest.resize(destLen);
             dest.swap(v);
         }

         res = [NSPropertyListSerialization propertyListFromData: 
[NSData dataWithBytes:&v[0] length:v.size()]  
mutabilityOption:NSPropertyListImmutable format:nil  
errorDescription:NULL];
     }
