On bash:

$ LC_ALL=C
$ ls
bar  BAT  cab  foo  ieee2000  MAC  moc  test  zac  zara  ZOO
$ ls *[a-z]
bar  cab  foo  moc  test  zac  zara
$ ls *[bd-z]
bar  cab  foo  test
$ ls *[^cC]
bar  BAT  cab  foo  ieee2000  test  zara  ZOO
$ ls *[^bc]
bar  BAT  foo  ieee2000  MAC  test  zara  ZOO

Since these are shell expansions you can also use them in loops etc relatively easily.

Note the LC_ALL=C setting - if you use a non-English locale it may be required in order to produce correct results:

$ echo $LC_COLLATE
en_US.UTF-8
$ ls *[a-z]
bar  BAT  cab  foo  MAC  moc  test  zac  zara  ZOO
$ LC_COLLATE=C
$ ls *[a-z]
bar  cab  foo  moc  test  zac  zara

As seen in the sample above you can set the more specific LC_COLLATE variable instead of LC_ALL.

EDIT:

By the way, at least on my system (Mandriva Linux 2010.1), the locale also affects grep:

$ LC_COLLATE=en_US.UTF-8
$ echo A | grep '[a-z]'
A
$ LC_COLLATE=C
$ echo A | grep '[a-z]'
$

You can use a combination of ls and grep with regular expressions:

ls | grep -e "[bd-z]$"
