The Wikipedia article on Israeli DST has a good discussion on why this is:

http://en.wikipedia.org/wiki/Israel_Summer_Time

To summarize, between 1992 and 2005, the start of DST was set by law, but the end of DST was ad hoc, at the whim of a government minister.

Since 2005, the end of DST is determined by the Jewish lunar religious calendar, so I'm not sure if this can be accommodated by tz automatically.

For Asia/Jerusalem (URL below) time zone -- DST begin date seems to be
consistently on the 'First Friday' following March 26th every year.   If
March 26 falls on Friday then DST begins on that Friday.   But I fail to
see any pattern in DST end date.   Currently, we have been defining new
time zone rule every year for Asia/Jerusalem in our metadata but want to
know if we can fit in some generic pattern to avoid maintenance.

Any suggestions ?
