Backticks mean you want your shell execute the command, but clearly shell is not there to do this when crontab job is executed. I would leave detailed explanation to someone more competent; but I can offer a workaround: Stick the redirection into your script:
Code:
 $ cat /home/mylogin/tests/script.sh
#!/bin/bash
(
 #whatever your script is doing
) > /home/mylogin/tests/`date +%Y%m%d`log.csv

This will run the body of the script in subshell and capture the output into the file

RunTargetUnitTests(1)					    BSD General Commands Manual 				     RunTargetUnitTests(1)

NAME

     RunTargetUnitTests -- run unit tests for the current target

SYNOPSIS

     RunTargetUnitTests

DESCRIPTION

     RunTargetUnitTests examines its environment and runs the unit tests it presumes are present using otest(1).

     RunTargetUnitTests is intended to be called from a shell script build phase.  It expects certain environment variables to be configured from
     Xcode build settings (see below).

     RunTargetUnitTests will run tests for all built architectures appropriate for the machine running the tests.

ENVIRONMENT

     ARCHS		 The architectures the tests were built for; when tests are run, they will be run once per architecture.  If unspecified,
			 tests are run for the architecture returned by arch(1).

     DEVELOPER_DIR	 The Xcode folder, e.g. "/Developer". If unspecified the value for SYSTEM_DEVELOPER_DIR will be used, or "/Developer" if
			 that also is unspecified.

     BUILT_PRODUCTS_DIR  The directory containing built products; when tests are run, this is specified in DYLD_FRAMEWORK_PATH.  If unspecified
			 tests are run from the current working directory with no DYLD_FRAMEWORK_PATH.

     FULL_PRODUCT_NAME	 The full name of the built product, including its wrapper extension if any.

     GCC_ENABLE_OBJC_GC  Whether or not the test bundle was compiled with Objective-C garbage collection enabled.  Possible values are
			 unsupported, supported, and required.	If not set, defaults to unsupported, which will run otest(1) with Objective-C
			 garbage collection disabled.

     NATIVE_ARCH_ACTUAL  The architecture of the machine running the tests, used to determine for which architectures tests can be run.  If
			 unspecified, defaults to the architecture returned by arch(1).

     OTEST		 The path to the otest command line tool; defaults to /Developer/Tools/otest.

     TEST_AFTER_BUILD	 Set to YES to run tests, any other value will prevent test execution.

FILES

     /Developer/Tools/RunTargetUnitTests  The script used to run tests from a shell script build phase.

     /Developer/Tools/otest		  The OCUnit test rig.
