According the root/includes/acp/acp_bbcodes.php file the maximun value for a bbcode id is set to 1511 :
Lines 207 to 210

					if ($bbcode_id > 1511)

					{

						trigger_error($user->lang['TOO_MANY_BBCODES'] . adm_back_link($this->u_action), E_USER_WARNING);

					}

In the mysql_41_schema.sql for bbcodes, the row for bbcode_id is defined as

bbcode_id tinyint(3) DEFAULT '0' NOT NULL,

But according the documentation from mysql :

TINYINT[(M)] [UNSIGNED] [ZEROFILL]

A very small integer. The signed range is -128 to 127. The unsigned range is 0 to 255.

source : http://dev.mysql.com/doc/refman/5.0/en/numeric-type-overview.html

May be the row have to be INT or SMALLINT

Like always, excuse me for my poor English, I speak Spanish.
