T-score is used when you don't have the population standard deviation and must use the sample standard deviation as a substitute.
There is an IQ Score Comparisons chart here: http://www.assessmentpsychology.com/iq.htm

T score was originally given to a type of normalized score based on a group of unselected pre-adolescents. Notwithstanding, it has come to refer to any normally distributed standard scores that has a mean of 50 and a standard deviation of 10. L F C
If the sample size is less then 30 use the T table, if greater then 30 use the Z table.

Because t-score isn't as accurate as z-score, you should use 40 as a safety sample size, rather than 30 as you would for a z-score.
T-scores and z-scores measure the deviation from normal. The normal for T-score is 50 with standard deviation of 10. if the score on t-score is more than 50, it means that the person scored above normal (average), and vise versa. The normal for Z-score is 0. If Z-score is above 0, then it means that person scored above normal (average), and vise versa.

26...a score = twenty (as in "...four score & seven years ago..." means 87 years)
The letter T is worth 1 point.

Because as the sample size increases the Student's t-distribution approaches the standard normal.
