Bash shell script (301 304 characters)
UPDATE: Fixed a bug involving pieces that extend into the top row. Also, the output is now sent to standard out, and as a bonus, it is possible to run the script again to continue playing a game (in which case you must add up the total score yourself).
This includes nonprintable characters, so I have provided a hex dump. Save it as tetris.txt:

Then, at the bash command prompt, preferably with elvis rather than vim installed as vi:
$ xxd -r tetris.txt tetris.sh
$ chmod +x tetris.sh

How it works
The code self-extracts itself similarly to how executable programs compressed using the gzexe script do. Tetromino pieces are represented as sequences of vi editor commands. Character counting is used to detect collisions, and line counting is used to calculate the score.
The unzipped code:
echo 'rej.j.j.:wq!m'>I
echo '2rejh.:wq!m'>O
echo '2rej.:wq!m'>Z
echo '3rejh1.:wq!m'>T
echo 'rej.j2.:wq!m'>L
echo 'l2rej2h.:wq!m'>S
echo 'lrej.jh2.:wq!m'>J
for t
do for y in `seq 1 5`
do echo -n ${y}jk$((${t:1}+1))l|cat - ${t:0:1}|vi b>0
grep ========== m>0||break
[ `tr -cd '#'<b|wc -c` = `tr -cd '#'<m|wc -c` ]||break
tr e '#'<m>n
done
cat n>b
grep -v '##########' b>m
$((S+=10*(`wc -l < b`-`wc -l < m`)))
yes '[ ]'|head -7|cat - m|tail -7>b
done
cat b
echo $S
The original code before golfing:
#!/bin/bash
mkpieces() {
pieces=('r@j.j.j.' '2r@jh.' '2r@j.' '3r@jh1.' 'r@j.j2.' 'l2r@j2h.' 'lr@j.jh2.')
letters=(I O Z T L S J)
for j in `seq 0 9`; do
for i in `seq 0 6`; do
echo "jk$(($j+1))l${pieces[$i]}:wq! temp" > ${letters[$i]}$j
done
done
}
counthashes() {
tr -cd '#' < $1 | wc -c
}
droppiece() {
for y in `seq 1 5`; do
echo -n $y | cat - $1 | vi board > /dev/null
egrep '={10}' temp > /dev/null || break
[ `counthashes board` -eq `counthashes temp` ] || break
tr @ "#" < temp > newboard
done
cp newboard board
}
removelines() {
egrep -v '#{10}' board > temp
SCORE=$(($SCORE + 10 * (`wc -l < board` - `wc -l < temp`)))
yes '[ ]' | head -7 | cat - temp | tail -7 > board
}
SCORE=0
mkpieces
for piece; do
droppiece $piece
removelines
done
cat board
echo $SCORE
