Yes, it's a bug.  And the test was wrong.

Here is a corrected version.  When the bug is fixed, the following should pass. 
 It currently fails because the first block returns 1 and the second block 
returns 1 2 3 (as seen in the quote).  Both blocks should return 1.

(ert-deftest test-cmdline-alone-and-with-shebang-have-same-result ()
  "Pass arguments to a block.  Don't use shebang.  Then use
shebang set to the same language as the block.  The result should
be the same."                                    
  (should (equal                                                    
           (org-test-with-temp-text
