Parent's c/f loss, minor's gain - can it be setoff?

A parent has a carried forward long term loss (shares, off market) in FY 2012-13. Can this loss be set-off against a minor's long term gain (shares, off market) for FY 2013-14?

Minor's income is clubbed with the same parent since many years. Logically it seems allowable. But law (and that too Income Tax!) isn't always logical.

Thank you :)
