Order logic does not work with multi-digit conditions

[TrangOul]

The following query works as expected:

new QueryBuilder(Account.class)
	.addField(Account.Name)
	
	.addConditions()
	.add(new QueryBuilder.SimpleCondition('Name = \'acc1\''))
	.add(new QueryBuilder.SimpleCondition('Name = \'acc2\''))
	.add(new QueryBuilder.SimpleCondition('Name = \'acc3\''))
	.add(new QueryBuilder.SimpleCondition('Name = \'acc4\''))
	(...)
	.add(new QueryBuilder.SimpleCondition('Name = \'acc12\''))
	.setConditionOrder('1 OR 2 OR 12')
	.preview();

Name = 'acc1' OR Name = 'acc2' OR Name = 'acc12'

, but if we change the order:

	.setConditionOrder('12 OR 1 OR 2')

, the query gets malformed:

Name = 'acc1'Name = 'acc2' OR 1 OR 2

, since 12 is replaced by {1}{2} in bracketConditions (and the subsequent 1 and 2 are left unbracketed ).
