Combining then sorting Javascript arrays. Getting unpredictable results

Combining then sorting Javascript arrays. Getting unpredictable results

this is how the data has been given to me, in an object w/ elements
separated by the pipe char.
first i need to combine the two array and then sort alphabetically. the
below example is a simplified example. but something is throwing the sort
function off. the results are bizarre
carriersOne = ['St. Joseph\'s Medical Center | New York Health Care
Insurance Company | Some Other Company'];
carriersTwo = ['Advantage Care | Chicago Insurance Company | Hospital
Insurance Corporation'];
carriersOne = carriersOne[0].split('|');
carriersTwo = carriersTwo[0].split('|');
allCarriers = carriersOne.concat(carriersTwo);
allCarriers.sort();
count = allCarriers.length;
for(i=0;i<count;i++) {
alert(allCarriers[i]);
}
What you get is: Chicago Insurance Company Hospital Insurance Corporation
New York Health Care Insurance Company Some Other Company Advantage Care
St. Joseph's Medical Center
w-t-bleep order is that? note: if you use single names, or predictable
first and last names, it combines and sorts fine.
