IMHO the OP wants to test this condition (in C style):

Code:
if (( "a" == rhino || "b" == crocodile ) && "c" == testsc )

The order of the test statements is significant, in the examples above the parentheses doesn't matter, but check the output of these commands:

Code:
$ bash --version
GNU bash, version 3.1.17(1)-release (i486-pc-linux-gnu)

$
$
$ if [ "a" = "b" ] && ([ "b" = "b" ] || [ "a" = "a" ]); then echo YES; fi
$
$ if [ "a" = "b" ] && [ "b" = "b" ] || [ "a" = "a" ]; then echo YES; fi
YES
$
