I don't think Google Apps Script can keep a persistent HTTP connection open which is resulting in the 504 (See Twitter Streaming APIs Doc)
[I've a basic retweet counter in this Google Spreadsheet Template (TAGS v4.0). The filterUnique formula uses this code (the pseudocode is strip out any links from tweet text then extract 1st 90% of text (to take account of any old style RT+ annotation), then if not in unique array add or add 1 to existing value):
function filterUnique(tweets){
var output = [];
var temp = {};
for (i in tweets){
if (i>0){
var tmp = tweets[i][0];
var urlPattern = /(\b(https?|ftp|file):\/\/[-A-Z0-9+&##\/%?=~_|!:,.;]*[-A-Z0-9+&##\/%=~_|])/ig;
tmp = tmp.replace(urlPattern,"")
tmp = tmp.substring(0,parseInt(tmp.length*0.9));
if (temp[tmp] == undefined){
temp[tmp] = [tweets[i][0],0];
}
temp[tmp] = [tweets[i][0],temp[tmp][1]+1];
}
}
for (i in temp){
output.push([temp[i][0],temp[i][1]]);
}
output.sort(function(a,b) {
return b[1]-a[1];
});
return output.slice(0, 12);
}
