Sequence filling puzzle

There was a puzzle shown in Sunday Magazine New Indian Express 20 july 2014 as follows-
What number comes next in the sequence 1,4,5,6,7,9,11..
Although I can give a hint that it is an alphanumeric sequence (Having connection with numbers and  alphabets) -it was truly  difficult to find the answer.
You will be surprised the next number is 100.
All the numbers shown in the puzzle when expressed in words do not contain the alphabet T.
The only next number with this quality as you can observe will be 100..
